A group including a man who took over a tourist bus were involved in "serious acts of violence" during a pro-Tommy Robinson demonstration in London, a court heard.

Seven men were jailed at Southwark Crown Court over the violent disorder in June 2018, which caused injuries to about 20 officers.

The "terrifying disorder wreaked by these individuals" was "inexcusable", the Crown Prosecution Service said.

Six others will be sentenced on Monday.

Prosecutor Aska Fujita told the court police had become "over-run" by disorder from those demanding the release of the ex-English Defence League (EDL) leader, whose real name is Stephen Yaxley-Lennon, from prison for contempt of court.

'Punched and kicked'

Chants rang out during the protest, while demonstrators could be seen on camera shouting "shame on you" at the police, adding, "you're not English any more" to the tune of a hymn.

"The police have been constantly abused, missiles were thrown at them, they have been punched, kicked and had barriers thrown at them," said Ms Fujita.

"The number of defendants does not reflect the actual occurrence of violence - police have tried incredibly hard to identify the people involved."

Detectives had to trawl through hundreds of hours of CCTV and videos to identify those involved.

"Each of the defendants were involved in serious acts of violence, including using weapons that could have caused serious injury," added Ms Fujita.
