Police were attacked with bottles and bricks by a huge mob of more than 400 people after being called to an out-of-control party on an estate in Hackney last night.

Scotland Yard said officers came under “sustained” attack during clashes on Sandford Court, off Bethune Road in Stamford Hill, as they were pelted with bottles, bricks and other items from balconies.

Many of those caught up in the violent disorder were wearing masks over their faces, police said.

One witness said: "It looked like the London riots four years ago, it was out of control."

Officers were called to reports of a raucous party on the estate at about 11.40pm on Saturday night.

A spokesman from the Metropolitan Police said: "When officers arrived, they were confronted by more than 400 people, many of whom were wearing face masks.

"Shortly after the officers arrived, they came under a sustained attack with bottles, bricks and other items thrown at them from balconies."

Riot police and dog units attended along with a police helicopter.

A spokesman added that several fights broke out between revellers attending the party while bins were pushed towards police vans.

Medics were seen treating one woman on a zebra crossing in the middle of the street.

The group was not dispersed until about 2am on Sunday, police said. Officers seized a knife which was found following a search of the area.

No officers were injured but a member of the public was treated by the London Ambulance Service after suffering breathing difficulties, police said.

Detective Chief Inspector Cath Edginton said: "A number of residents had contacted police to complain about the noise levels at the party and it was for this reason that officers attended.

“To be confronted by hundreds of people and attacked in this way is wholly unacceptable.

"It is fortunate that none of my officers were injured.

"I would also like to take this opportunity to appeal to anyone who witnessed the events or has information about the people responsible to contact the police."

Police have launched an investigation and are appealling for anyone with information to come forward.

No arrests were made but enquiries continue to trace those involved.
