Here at Newscast, we have been reporting on the man who was arrested on suspicion of attempted murder after a car was driven into a crowd of fans during the Liverpool FC victory parade on Monday night.

The suspected driver, a 53-year-old from West Derby, in Liverpool, has also been arrested on suspicion of driving while unfit through drugs and dangerous driving offences.

More than 50 people were injured after the incident - but police say the 11 people who remain in hospital are all in a stable condition.

How was this able to happen?

Adam Fleming speaks to BBC Breakfast presenter Sally Nugent - who spent the morning reporting live from the scene of the crash - and long-time home affairs correspondent Tom Symonds to try and get some answers.

We heard earlier that Jack Trotter, a Northern Irish man who was at the LFC parade, had left hospital after being hit by the car.

He told the BBC he had travelled to Liverpool with his girlfriend Abbie Gallagher - both from Newtownards, County Down - who was also struck by the vehicle.

Now, speaking to us again, he explains his mindset when the collision occurred. "The first thought that I got was: 'Where's Abbie? I need to find Abbie.' You know she could be anywhere at this rate and lucky enough she was screaming my name and I found her."

Abbie says Jack then fell against a wall and began crying, saying that his back and leg were in pain. Jack was taken to hospital and kept in overnight - he is now walking with crutches.

"Keep your loved ones close, that's the main thing," Abbie says of what happened. "Honestly, you just have to be grateful ... and realise that it can all be taken away from you so quickly."

Within hours of a car driving into a crowd during Liverpool FC's victory parade, Merseyside Police announced they had detained a man.

They later confirmed that the man had been arrested and was the suspected driver of the car.

Here's everything we know about him so far:

• He is a 53-year-old white British man - our correspondent earlier looked at why police had released these details so quickly
• He is from the West Derby area of Liverpool
• He has been arrested on suspicion of attempted murder, driving while unfit through drugs and dangerous driving offences
• Police are not treating the incident as terror-related

Was a social media frenzy quelled here - or not?published at 18:30 British Summer Time

Over the past year - including after the attack in Southport last summer - vacuums of information have left room for online frenzies of disinformation, unfounded conspiracy theories and widespread speculation, often mixed in with valid questions and concerns.

Following the Liverpool parade crash, the police’s decision and ability to share more information quickly about the suspect appears to have quelled such rumours.

That said, the speed at which clips of the incident spread online did add fuel to the fire. And regardless, the same blueprint of unfounded speculation, conspiracy theories and disinformation have been circulating on social media all day.

Take - for example - a clip of a younger man messing about in a police car from earlier in the day, which people then suggested was actually the driver of the car.

Lots of this content is actively promoted by algorithms - recommendation systems - on some of the social media sites because it gets eyeballs and clicks.

Some of these posts, videos and memes play on existing distrust in the police and authorities - in some cases spreading extreme conspiracy theories that the attack was staged in some way, rather than genuine questions about safety around the parade.

Everyone can become their own investigator - sharing footage or speculating about motive. That's something police have warned against out of respect to those injured and their families.

We’ve been looking at a seven-minute video which shows the unfolding chaos after a car ploughed into a crowd yesterday in Liverpool.

We’ve confirmed it was filmed on Water Street. Here are some key moments:

The suspected driver

Several police officers can be seen pulling the suspected driver from his seat while holding back the crowd, some of whom climb through the passenger side to reach him. It takes five minutes for six officers to move him to the rear of the car and away.

Person under the car

Onlookers, police and medical staff attend to a person beneath the front of the car, then others try desperately to lift it from the passenger side. Several emergency workers continually look underneath the rear of the vehicle.

Other injuries

Near the car, a person lies on the ground. Someone in a red top joins them while others protect them from being trampled on by the crowd. At least two more injured groups can be seen further along the road.

We can now bring you pictures of Home Secretary Yvette Cooper, who has been visiting the site where a car drove into a crowd at the Liverpool FC parade on Monday.

She was seen walking around the area, which remains cordoned off to the public, with Liverpool City Region Mayor Steve Rotheram and Merseyside Deputy Chief Constable Chris Green.

She has also been meeting first responders to thank them for their work.

We've just received some more pictures from the area around Water Street, where members of the public have begun to lay flowers, cards and toys near the scene where a car drove into a crowd.

As a reminder, police said earlier today that 50 people were treated at hospitals following the incident. Eleven people remain in hospital and are in stable condition.

BBC Verify has examined videos of the incident in which a car was driven into a crowd in Water Street yesterday.

A BBC reporter on the scene, Matt Cole, said the car initially was being chased by a group of men "who were trying to bang on the side of it and throw things at it".

It then swerved into the pavement after colliding with pedestrians and got back on to the road, leaving several injured.

Merseyside Police says the driver followed an ambulance, which was heading to treat a member of the public for a suspected heart attack, after a road block was temporarily lifted.

Here's a map showing the car's journey:

Merseyside Police is asking people who have information about the car that was driven into a crowd in Liverpool to refrain from sharing it online and instead pass it on to their investigation team.

"Information, including video footage, can be passed on via the Major Incident Police Portal (MIPP)," the force says.

People are able to submit any relevant material via this link, external or they can contact Crimestoppers anonymously on 0800 555 111.

Let's bring you more reaction from those connected to Liverpool Football Club.

Reds legend and former captain Steven Gerrard posted on Instagram this afternoon that he was “shocked, sickened and saddened” over the incident.

He says his “thoughts and prayers go out to all the people involved and their families".

It follows similar messages of solidarity from former manager Jurgen Klopp, captain Virgil Van Dijk and club icon Sir Kenny Dalglish.

Meanwhile, the Spirit of Shankly, Liverpool FC's official supporters' union, says it's proud of how the city has responded and has urged people to share information directly with police, and not to speculate online.

Daniel Eveson from Telford tells the BBC that the car which drove into the crowd hit him in the chest and his partner was "dragged down the road" under the wheels.

He was walking at the parade with his family when the incident happened.

"My partner went under the wheel and the car went over her leg," he says.

"It was terror, pure terror."

Eveson's baby son's pram was then tossed about 4.5m (15ft) down the street.

For a moment, he did not know if his partner or son had survived, he says.

"I saw a gentleman on the bonnet and the rest was just chaos," he tells BBC Radio Shropshire.

Eveson says his partner was taken to hospital and he is waiting to hear when she can come out. It was the "worst day of my life", he says, and he'll never go back to a football parade.

She is expected to visit the police cordon where a car was driven into a crowd during Liverpool FC's Premier League victory parade.

She is also expected to meet emergency personnel.

As we reported a bit earlier, the road block on Water Street - the site of yesterday's incident - was temporarily lifted by event organiser stewards to allow an ambulance to get through.

Police said in their news briefing earlier that the car is believed to have followed the emergency vehicle onto the street that had previously been blocked.

That vehicle is believed to be the only one to follow the ambulance through the roadblock, a spokesperson for the Merseyside Police added.

There is an extension until Wednesday at lunchtime to question the suspect, a Merseyside Police spokesperson says.

A reminder, police earlier said a 53-year-old male suspect was arrested yesterday on suspicion of attempted murder, dangerous driving offences and driving while unfit through drugs.

Merseyside Police have just ended their news conference after a car was driven into a crowd at the Liverpool FC parade in the city's centre on Monday evening. Here's a summary of what we heard:

• A 53-year-old male suspect has been arrested on suspicion of attempted murder, dangerous driving offences, and driving while unfit through drugs, police say
• The suspected driver of the car is believed to have followed an ambulance onto Water Street, which had previously been blocked. Access had been temporarily lifted to the emergency vehicle so first responders could attend to a person suffering from a suspected heart attack
• Fifty people were hospitalised and 11 of these patients remain in hospital - all are in a stable condition and "appear to be recovering well", authorities add
• Police say they will continue to support the victims of the attack, while an extensive CCTV search is ongoing to understand the driver of the car's movements
• The police repeated that the incident is not being treated as terrorism, and urged the public not to share distressing content online or speculate about the motivations behind the incident

We'll continue to bring you further updates as we digest what we've just heard.

Detective Chief Superintendent Karen Jaundrill says police will continue to support those injured "in the days and weeks to come".

She says Merseyside Police have received assistance from neighbouring forces, and detectives are speaking to witnesses and emergency responders to build a full picture of what happened.

She adds that "extensive" CCTV inquiries are being made to track the movements of the Ford Galaxy leading up to the incident.

The news conference with the Merseyside Police has now ended. We'll continue to bring you updates in the next few posts - stick with us.

A 53-year-old man from West Derby has been arrested on suspicion of attempted murder, dangerous driving offences and driving while unfit through drugs, police say.

Assistant Chief Constable Jenny Sims then confirms on behalf of the NHS that 50 people were treated at hospitals following the incident.

Of these, 11 remain in hospital. All are in a stable condition and appear to be recovering well, she says.

Sims then pays tribute to members of the emergency services who immediately ran to a "dangerous situation" and were on the scene in seconds.

Assistant Chief Constable Jenny Sims of the Merseyside Police now says that they believe the driver of the car was able to access the road after following an ambulance that was attending to a member of the public who was having a suspected heart attack.

Access on Water Street, which was blocked she says, was temporarily lifted so that the ambulance crew could attend to that individual.

As with all large events we have armed policing presence throughout the day. There was no intelligence that an incident of this nature would take place - it is not being treated as terrorism.

Sims says there is an extensive investigation into the incident now under way in Liverpool.

She asks people not to speculate on the circumstances surrounding the incident and again asks the public not to share distressing content online.

"I have no doubt regarding the impact that this appalling incident has had on those who were injured, their family and friends," she says.

She adds that it's heartening the "human impact" on emergency services has been recognised, and thanks the public.
