Ely resident Rob says he and his partner tried to leave their home with their newborn baby and two other children at about 01:00.

But the way was blocked by police in one direction and a burned car in the other.

Officers, he said, told them to leave on foot.

He said: “We couldn’t get out, we were stuck. I carried my three kids to my dad’s [house] a few streets up."

He said they were terrified.

"I ended up stood outside in my front garden, you had to protect your house," Rob said.

Ely resident Vikki Takata says she saw "loads of riot vans" when looking out of her window last night.

A helicopter, she says, was "shining the torch down on us".

"It was carnage... I've never seen anything like it other than on the telly," she added.

"The police with the shields were all literally opposite my car."

Tomos Morgan reports from Ely in Cardiff where two teenagers died in a crash before a riot broke out.

A resident named Dean says he heard "cars on fire" and "explosions on Stanway Road” at between 19:00 and 20:00.

The 34-year-old was at home with his partner and two young children.

He said: “Then about 10:30 I heard the helicopters above and sirens, police telling people to get away from the cars and the explosions.

“There was smoke billowing from the street, it was absolutely atrocious.

“It makes you wonder if it’s going to happen again."

The CCTV footage appearing to show a police van following the scooter or electric bike was recorded on Frank Road - about half a mile from the crash.

The video's time stamp shows it was recorded at 17:59 on Monday, shortly before the fatal crash on Snowden Road in Ely.

Police refuse to answer questions about CCTV footage appearing to show moments before the Cardiff crash.

The Independent Office for Police Conduct (IOPC) has issued a statement after South Wales Police referred itself to the police watchdog.

It says: “We have been contacted this afternoon by South Wales Police to make a referral regarding the circumstances leading up to the fatal collision in Ely yesterday.

"We will be sending investigators to a police post-incident procedure to begin gathering information and to assess whether the IOPC will carry out an independent investigation.”

There's a lot of people out on the streets already tonight questioning what happened last night.

Ely has had a reputation over the years. The Ely riots took place almost 32 years ago.

It took a number of years for the community here to get rid of that reputation, but it also has a reputation as a close-knit working-class community and I've seen that as the day has gone on.

Flowers have been laid in the street where those fatalities took place. Earlier today, friends and families have come together to grieve together.

But people have also spoken about a distrust in the police and the way things have transpired today.

This morning South Wales Police hadn't referred themselves to the IOPC, but has since said it has.

So there will be distrust and there will be anxious voices here again tonight because they will want answers.

There'll be sympathy for the families and sympathy for the residents here after what has been a very difficult 24 hours.

There are a lot of questions tonight, especially in this area.

When we arrived here this morning, there was dismay really from the residents on the street because so much of their property had been damaged by the riots that happened last night.

And the rumours were rife, rumours that the police had, in some way, been involved in the death of the two boys which happened hours before the riots began here in Cardiff.

New footage has now come to light and seems to question the version of events given by the police in the run up to the two teenagers' death yesterday.

Calls have been made by politicians for an impartial investigation into police handling of events in Cardiff.

Following the emergence of CCTV, which appears to show a police van following two people on an electric bike before the crash, the Welsh Liberal Democrats have urged South Wales Police to publish their timeline of events.

Cardiff Liberal Democrat leader, Rodney Berman, says there are "serious questions" over the police version of events.

“This incident needs to face an immediate, impartial investigation," he said.

Plaid Cymru MS for South Wales Central Heledd Fychan echoed Mr Berman's sentiments, saying an independent investigation was "essential".

South Wales Police has referred itself to the Independent Office for Police Conduct (IOPC).

The BBC has spoken to a man who lives near the crash and scene of the riot in Ely and described what he saw last night.

Felix, who asked we do not use his full name, said he didn't hear the crash but saw traffic "piling up on the bottom of my road" at some point between 18:30 and 19:00, followed by "shouting and some screaming" a few minutes later.

He says after going to see what was happening, he saw "numerous police officers and dozens of people gathered round", but at that point he says there was "only slight disorder" - rather than arson or vandalism.

But Felix also says around an hour or two later he heard "significantly more shouting, and then a few screams".

We've just heard from South Wales Police about last night's incidents in Ely, where riots broke out after a fatal crash involving two teenagers.

Here's what we heard:

• Ch Supt Martyn Stone issued a short statement about the investigation into the crash which killed Kyrees Sullivan, 16, and Harvey Evans, 15, and sparked subsequent riots

• He confirmed police had received CCTV footage that shows a police vehicle following a bike
• Police are examining the footage, but Ch Supt Stone added there were no police vehicles on the road where the incident happened at the time of the crash
• During the brief statement readout, he confirmed arrests had been made following the riots, in which 11 officers required hospital treatment
• He did not take questions from the gathered press, but said the force had made a mandatory referral to the Independent Office for Police Conduct (IOPC) "to ensure the matter receives independent scrutiny"

Moving away briefly from reaction to the press conference, let's bring you some more comments from last night - this time from the mother of Kyrees Sullivan.

Shortly after midnight Belinda Sullivan wrote on Facebook: "My son is still laying on the floor due to this riot. I'm sat at home heart-broken.

"There are two families broken right now I just want to see my son and I can't because of this riot that has happened.

"Please I beg you all to stop and let my son be moved to hospital so I can see him we need to see our sons."

South Wales Police and Crime Commissioner Alun Michael declined to comment on social media footage appearing to show a police van following two people on either a moped or electric bike, apparently minutes before the crash.

He said: "You should examine the carefully-worded statement from the chief superintendent."

A bit more from South Wales Police's update from a few minutes ago.

Ch Supt Martyn Stone said there were "no police vehicles on Snowden Road" when the crash happened, adding officers did not believe any other vehicles were involved.

Later in the brief statement, he said the force had made a mandatory referral to the Independent Office for Police Conduct (IOPC) "to ensure the matter receives independent scrutiny".

Ch Supt Stone left abruptly after reading his brief statement.

He did not take questions about the CCTV footage of the bike being followed by a police van.

Stone says he acknowledges the impact of last night's events on local residents "who were understandably very frightened".

He adds the police are doing their best to find those responsible, saying: "A number of arrests have already been made, and more will follow."

Ch Supt Stone says 15 officers were injured, 11 went to hospital for treatment as a result of the riots.

Police are appealing for witnesses and footage from social media and phones, he adds.

We're now hearing a bit more from Ch Supt Martyn Stone, who says that at 18:03 BST yesterday they received the report of a collision.

He says police are looking into the footage and families are being kept up to date.

"We've received CCTV footage that shows a police vehicle following a bike, at just prior to 6pm," he says.

"This footage is being recovered as part of the investigation and will assist us in piecing together the circumstances."

He adds that when the collision occurred, "there were no police vehicles on Snowden Road".

Officers performed CPR, he adds, and at this stage Stone does not believe any other vehicles were involved.

They're also appealing to witnesses to come forward.

South Wales Police are giving an update now.

Ch Supt Martyn Stone says police are continuing to investigate the crash and disorder in Ely.

He says officers received reports of a crash just after 18:00 yesterday and an electric bike was seized from the scene.
