Images of 10 people the Met want to find after violence broke out at a “Free Tommy Robinson” demonstration in central London have been released.
More than 20 officers and members of the public were injured as protesters blocked roads and threw missiles during the march in Whitehall on 9 June, 2018.
Detectives had to trawl through hundreds of hours of CCTV and videos to identify those involved.
Fourteen people have already been jailed over the violent disorder.
Referring to the incident where scaffolding and glass bottles were thrown at police, Det Sgt Matt Hearing said: “We are extremely keen to identify these individuals, who were involved in serious disorder which resulted in a number of police officers getting injured.
“Whilst we will always facilitate lawful protest, the actions of some individuals on that day showed a total disregard for the law and it is important that all those involved are brought to justice.”

The nine month sentence includes six months for the Leeds Crown Court offence last year and another three months for contempt of court, following a suspended sentence given at Canterbury Crown Court in May 2017.
