A clean-up operation is under way after widespread disorder saw a police car flipped and a double-decker bus torched on the streets of Harehills.

The disturbance started on Thursday evening and spread into the early hours with hundreds of people gathering in the area.

West Yorkshire Police have made "several" arrests, with more expected in the coming days.

Here is what we know so far:

What caused the violence?

Police said officers were called to an address in Harehills, at 17:00 BST on Thursday, where they found an “ongoing disturbance” involving “agency workers” and children.

Witnesses described children and social workers being removed from a house by police, sparking the unrest.

West Yorkshire Police said it believed the disorder was caused by “a criminal minority intent on disrupting community relations”.

How did the unrest spread?

Police initially described "pockets of disorder" breaking out but as the evening progressed, the scenes became increasingly violent.

Social media footage showed the windows of a police car being smashed before a group of people lifted it up and tipped it over.

A First double decker was torched and destroyed and a number of other fires were lit as the evening progressed.

What has been the reaction?

The prime minister and home secretary have condemned the attacks.

Sir Kier Starmer said police would have the government's "full support" in investigating the incident.

More locally, leaders and community figures spoke out about the disorder.

Mayor of West Yorkshire Tracy Brabin said she was "appalled" by the scenes while Leeds City Council chief executive Tom Riordan said it was triggered by a family incident.

He said: "This is not a community where this happens regularly. This is a very diverse community that generally gets on well."

Richard Burgon, MP for Leeds East, said residents had told him they were "devastated" by the events in Harehills.

"So many good people worked together to try to calm things and reduce disorder in the community they care about so much," he said.

Police said they would "leave no stone unturned in our hunt for all those who were involved".

Tracy Brabin says there will be "reassurance patrols" in Harehills tonight and over the weekend to prevent any further disorder.

"We know that community members and youth workers and councillors are out and about reassuring people and encouraging them to do the right thing and to stay off the streets."

The mayor says she has held talks with "key partners" and a plan is being drawn to keep Harehills safe.

Ms Brabin says: "The imams and the faith leaders are also getting the message out there that we need to stay calm and ensure we don't have what we saw, which was frightening, horrible and unacceptable."

West Yorkshire Mayor Tracy Brabin has appealed for calm after the disorder in Harehills and called on parents to make sure their children are not on the streets.

Speaking during a press conference, Ms Brabin says she has visited the area with her deputy Alison Lowe to offer support.

She says the disorder was "so distressing for the community" and that it was carried out by a "criminal minority".

"I want to publicly commend those people who throughout the night were on the streets ensuring that the outcome wasn't worse than the outcome we saw. They went above and beyond."

The mayor adds: "I also want to strongly urge calm and say to parents, please, please make sure that your youngsters are home with you and not on the streets."

Craig Nicholls says the officers who dealt with the Harehills disorder are "everyday heroes".

Mr Nicholls says it was a "troubling experience" for their families as they did not know if the officers would walk through the door at the end of their shift.

Asked about criticism of officers on social media, he says: "It's all very well sat behind a keyboard and a comfy sofa typing away with very or little backlash

"But come and walk a mile in our shoes."

The chairman of the West Yorkshire Police Federation says it was "shocking" to witness the disorder in Harehills.

Craig Nicholls tells the BBC: "The police vehicle that was overturned and damaged is used in response to a 999 call - so that's one less resource we have of a finite resource

"We don't have an abundance of police vehicles."

He also says it must have been "very frightening" for those in the community to witness such violence.

He adds: "A small minority of people wanted to cause that level of damage."

Morrisons in Harehills has closed for the rest of the day.

Security on the door tell the BBC the move is "for the protection of their staff" in case of further disorder.

The council says communities "play a vital role" in keeping neighbourhoods safe.

It adds: "We are immensely grateful to those key individual networks of individuals, community leaders and elected officials within Harehills who rallied together last night to help to do this and prevent the situation from worsening alongside the police.

"We would urge people living in the Harehills community to stay safe and follow the latest police advice, we would also like to thank all the agencies for their response, and members of the community."

Leeds City Council says it is working with police, community leaders and other agencies in response to the disorder.

Posting to social media, the council says: "Incidents like this do not reflect Leeds or the Harehills community as a whole.

"While this is an ongoing police matter, it would not be appropriate to comment further on any alleged circumstances surrounding this incident.

"However we would ask people to avoid engaging with speculation on social media to enable people to engage with local services where they need to."

Drone footage taken earlier today shows the charred remains of the bus that was set alight during the disorder on Thursday.

First Bus has confirmed that two of its vehicles were caught up in the trouble, one of which was later set on fire, but said that nobody was injured.

The remains of the bus have been loaded on to a ramp for removal from the scene.

The police cordon has been extended to allow employees from Leeds City Council to clean up the debris that has been left behind.

Police in Harehills are working to remove the bus that was set on fire during last night's disturbance.

Officers are attempting to remove it using a yellow forklift truck.

Some of the bus is being sprayed with water to cool it down, while a chain has been attached to the front to allow for easier removal.

West Yorkshire Police Assistant Ch Con Pat Twiggs outlines the order of events in Harehills last night, as he confirms several arrests.

• Officers responded to a call from children’s social care at around 5pm yesterday after social workers reported being met with hostility when dealing with a child protection matter.
• Responding officers were attacked and helped children’s social care staff withdraw to a place of safety.
• As the disorder escalated, damage was caused to vehicles and several fires set.
• Specialist public order officers came under a barrage of bricks and missiles from a large group.
• A decision was taken to withdraw these officers temporarily "as it was evident that the police was their sole target".

Mr Twiggs said withdrawing the police officers "allowed for further community mediation to take place in order to calm the situation".

He added: "Police then returned to the area with fire colleagues to extinguish the remaining fires which were self-contained and didn’t pose a wider risk.

"By this point the crowd had diminished and officers were able to fully restore order.

"Throughout the night several arrests were made in relation to the disorder and further arrests will be made over the next few days."

Several buses have been diverted in and around Harehills today and Saturday to protect the safety and wellbeing of staff, an operator says.

A double decker bus was torched during the violence on Thursday night.

First Bus says the following services are affected by the diversion: 4/4F/12/13/13A/16/42/49/50/50A and 91

A spokesperson says: “We are diverting services that go into or around the Harehills area from 2pm today and this will remain in place through the night and be repeated at the same time on Saturday.

“This decision is for the safety and wellbeing of our colleagues and customers.

"We appreciate that diversions will cause disruption but would like to thank in advance, all passengers and the local community for their patience and understanding while these changes are in place."

The spokesperson says customers are advised to check before travelling on affected services.

Assistant Ch Con Pat Twiggs said public order officers "came under a barrage of bricks and missiles from a large group".

He said police were withdrawn "as it was evident that police was their sole target" but restored order once the crowd had diminished.

Several arrests have been made in relation to the disorder last night, police say.

Pat Twiggs, assistant chief constable at West Yorkshire Police, said: "Throughout the night several arrests were made in relation to the disorder and further arrests will be made over the next few days.

"We will leave no stone unturned in our hunt for all those who were involved and will work closely with our criminal justice partners to bring them to justice."

Downing Street said the government would not "cut across a police matter" when asked whether it would support fast-tracked sentences for anyone found to have broken the law.

When he was director of public prosecutions in 2012, Sir Keir said rapid prosecutions were more important than long sentences.

Asked whether the Prime Minister would back fast-track sentences now, the Downing Street spokeswoman said: "On this case, we'll let the police carry out their work and they have our full support in doing that."

Prime Minister Sir Keir Starmer has condemned the "shocking and disgraceful" disorder seen in Harehills.

Pointing to the home secretary's statement on the violence, a No 10 spokeswoman said: "He would echo that the scenes that we saw last night were shocking and disgraceful. And disorder of this nature has no place in our society.

"That's why he would like to thank West Yorkshire Police and the emergency services for their swift support.

"And the police have our full support in carrying out their investigations and taking the strongest possible action against perpetrators and keep the public safe."

Asked about fears of community tensions being inflamed, she said: "The police have discouraged people from speculating on the cause of the disorder.

"And the Prime Minister would also urge people to follow this advice.

"But certainly, as the home secretary I think also outlined this morning, local partners and councillors will be working very closely with the community today to provide support and reassurance in light of the shocking scenes that we saw last night and prevent further disturbances."
