Summer riots: new images released by police
Detectives have released another 32 images of people wanted over this summer's disorder in the West Midlands as the investigation into what happened continues.
Three months have passed since the disorder and looting that took place in Birmingham, Wolverhampton and Sandwell and hundreds of people have been arrested, however many offenders remain outstanding.
On Wednesday 9th of November around 70 officers raided addresses in Wolverhampton and Birmingham resulting in 15 arrests and the recovery of numerous pieces of evidence.
It was the third phase of a co-ordinated set of arrest missions planned in an attempt to process suspects as efficiently as possible through the criminal justice system.
The day of action means that the total number of people arrested in connection with the disorder now stands at 686.
Detective Chief Inspector Steve Reed, who is leading the operation, said: "It's been three months since the disorder but this investigation simply will not end until every avenue to identify and arrest suspects has been exhausted.
"The communities of the West Midlands have very clearly told us that they want justice to be done and we are committed to making sure that happens.
"My message to anyone involved in the disorder who has not yet been arrested is that it is only a matter of time before we come knocking on your door.
"I would encourage everyone to log on to our website, look at the newly released images and get in touch if you recognise anyone."
Anyone who recognises anyone in the images is asked to contact officers from Operation View on 0345 113 5000 or the independent charity Crimestoppers anonymously on 0800 555 111. Alternatively they can email email@example.com.
