Eight people have been arrested in dawn raids by detectives investigating violent clashes which broke out at an English Defence League (EDL) rally in Walsall.
The suspects, aged between 17 and 58, were detained early on Tuesday at addresses in Tipton, West Bromwich, Brownhills and Birmingham, West Midlands Police said.
A total of 30 arrests were made at the time of the clashes between EDL protesters and counter-demonstrators in Walsall town centre on September 29 last year.
Detective Inspector Pete Dunn, who is leading the police investigation into the disorder, said: “The majority of the people attending these demonstrations were law-abiding, however small numbers of people decided to get involved in a few ugly scenes when people began to try to break through police lines and were throwing missiles.
“Since September we have been working to identify others who were involved in the disorder and now we have been able to make further arrests.”
In addition to the latest arrests, West Midlands Police has released ten images of men detectives want to identify as part of the ongoing inquiry.
Mr Dunn added: “We urge anyone with information as to who these men are to contact us as soon as possible.
