Police are seeking to identify 10 people after more than 20 officers were injured at a "Free Tommy Robinson" demonstration in Whitehall.
Violence broke out on June 9 last year when supporters descended on Westminster to protest against the imprisonment of the EDL founder.
Robinson, real name is Stephen Yaxley-Lennon, had admitted contempt of court after broadcasting details of a trial that was subject to reporting restrictions.
Scaffolding, glass bottles and barriers were thrown at officers during the demonstration.
At the time, the Met Police launched "Operation Augusta" to investigate the violence, releasing pictures of nine people they wanted to identify. Nine people were also arrested on the day itself.
Today, the force's public order crime team released new images of 10 more individuals it wants to identify.
Det Sgt Matt Hearing, who leads the Operation Augusta team, 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.”
Anyone with information is asked to contact the Met’s public order crime team on 020 8246 0076 or Crimestoppers anonymously on 0800 555 111.
