Police release riot pictures
Police investigating the violent disorder in Bristol on Thursday night have released pictures of people they want to speak to.
Around 400 people were involved in rioting after a peaceful protest escalated into violence in the Stokes Crost area of the city.
Police made a total of around 30 arrests through the disorder, and in the subsequent eviction on Friday of a property in Cheltenham Road thought to be connected with the disorder.
Assistant Chief Constable Rod Hansen said: "We are doing everything we can to identify these people, but we cannot do it all alone.
"So I am appealing to the community, to all the residents, and traders and other people whose lives have been severely disrupted, whose property may have been damaged
and whose personal safety may have been put at risk by the violence: help us bring those responsible to justice.
"Give us the information we need to find them and arrest them; send them a very strong message that the wider community finds their violent behaviour unacceptable, and that it will not be tolerated.
"I would urge people to study these photographs, and if you think you know who any of these people are, and where they might be, please contact us, so that together we can prevent a repeat of the violence we've experienced.
"If you are one of the people pictured here, my message to you is come forward now and give yourselves up. It is only a matter of time before we catch up with you."
Anyone who does have information about the identity of any of these people should call Crimestoppers on 0800 555 111 , contact police on-line at www.avonandsomerset.police.uk/contact or by calling 0845 456 7000 .
