Police have appealed for help to identify a dozen people after a McDonald's store was "ransacked" during a night of violence in Hyde Park .

Video footage appeared to show people storming the fast food outlet at Marble Arch and helping themselves to food on Tuesday (July 19) evening.

The looting happened on the same night a "water fight" in Hyde Park descended into violence, which resulted in a police officer and two other people being stabbed.

Police have also released CCTV images of suspects believed to have been involved in the violence in Hyde Park.

Detectives investigating the disorder at McDonald's have released images of 12 people they want to identify.

Warning to parents over illegal raves

The appeal came as the Met urged young people not to attend illegal raves and other unlicensed music events, telling them "it's simply not worth it".

Officers also called on parents to keep an eye on their children and ensure the events they are attending are above board.

They said if the event and venue details were not advertised well in advance, tickets were not sold or there was no published line-up of artist it was probably an unlicensed event.

"There will be no security, no first aid and no license. Illegal drugs and the previously so-called legal highs are prevalent at these events," they advised parents.

"Psychoactive substances were linked to more than 100 deaths last year in the UK alone and unfortunately young people are often the victims of this.

"They are advertised at short notice and often attract trouble. People have been seriously hurt and arrests are made - which has a huge impact on a youngster's future."

'Attending a rave could put yourself and friends in danger'

In their message to young people, police said: "London is a great cultural city with hundreds of reputable and professional venues, clubs and music events.

"So think carefully about attending an illegal event that could put you and your friends in danger and could have a serious impact on your future. By any measure it’s simply not worth it."
