Police investigating the riots led by the far right say they have made more than 700 arrests for alleged offences, and promised “hundreds” more to come. Of the 741 arrests, 32 relate to online offences such as incitement, and the scale of the operation is shown by the fact the arrest took place in 36 of the 43 force areas across England and Wales. Arrests include allegations of violent disorder, theft and antisocial behaviour, and police say the investigations across the country will probably last for months to come. The figures come as communities and forces brace for more potential gatherings that could tip into violence, with police continuing with their biggest mobilisation to face down a public order threat since the 2011 riots across England. Police said 302 people had been charged, with more to come, and said further cases should be expected against “rioters and those spreading online hate”. The new figures were issued by the National Police Chiefs’ Council (NPCC). The figures include Northern Ireland, where police have arrest 26 people and charged 21 in relation to rioting. Detectives are using a variety of sources to identify suspects, including drone and body-worn video footage. BJ Harrington, a chief constable who is the national lead for public order, warned that facial recognition, which is being used retrospectively, can identify people even if they are wearing masks. Police chiefs are convinced their constant public messages about swift and robust justice will continue to act as a deterrent to some who may be tempted to join in the violent disorder seen in England and Northern Ireland since last Tuesday. The latest police statement is part of that campaign. The violence broke out after false information about the suspect of the stabbings in Southport that left three young girls dead was widely shared online. The violence has in part been stoked by the extremist far right, and has involved a strong anti-Muslim and anti-immigrant sentiment. Some people arrested joined in spontaneously, police believe. The past two nights have been quieter, but police said 6,000 riot officers would be deployed over the weekend as officers wait to see if the worst of the violence has passed. Gavin Stephens, the NPCC chair, said: “While the previous two nights have been a welcome break from the appalling scenes of the last week, and may have reached a turning point, we are by no means complacent. “Our message to those involved in violence is that we continue to comb through thousands of images, live streams and videos as well as body-worn footage to find you. “We are grateful to those who are calling us to identify those in the images circulated by forces. We are also grateful for the many messages of support to the officers, staff and volunteers that have faced hatred, racial abuse and violence whilst doing their job.” Police declined to say how many potential gatherings they expect this weekend. Police saysaid they expected 160 far right-led gatherings on Wednesday but only 30 happenedtook place with little or no incident, and with anti-racists taking to the streets to defend those under attack. Stephens said: “The strong message that communities sent on Wednesday evening that they don’t tolerate hate and racism and violence, also, as potentially the start of a turning point in this whole thing. “So, I think the mood is different as a consequence of all that.” Harrington said: “I would not say we are not worried. But what we are is prepared … policing’s got a grip of this.” Stephen Parkinson, the director of public prosecutions, said: “More than 100 extra CPS prosecutors stand ready to respond rapidly to emerging requirements for charging decisions and advice. “We understand the deterrence impact of a swift and robust response from law enforcement. Our aim is to make immediate charging decisions where we can, to enable courts to sentence within days.”
