This shocking footage shows a rampaging mob launch a series of sickening attacks in east London's Brick Lane.

Police have launched an investigation after a series of up to three attacks earlier this week.

In one of the assaults caught on film a man is beaten over the head with a road sign, while another shows a bare-chested victim being repeatedly kicked in front of a baying mob as he cowers on the pavement outside a curry house.

Video footage of the first attack shows a man being kicked and punched next to roadworks hoardings as he tries to flee the scene on Monday night.

As one of the victims runs along the road to try to escape, the first continues to suffer blows from a splinter group of up to three men.

The second victim, wearing a dark jacket and grey hooded top, is then wrestled to the ground and punched, before another of the attackers sets upon him with a road sign.

After two blows to his head, the victim is shoved and stumbles along the road, falling over before apparently fleeing the scene.

In another - apparently linked - attack, a crowd of up to 20 people are seen gathered outside the Eastern Eye Balti House as a bare-chested man is repeatedly kicked in his head and body as he lies almost motionless on the ground.

Several men are heard shouting “this is Brick Lane, mother f***er” as the attack continues.

As the man is left barely able to move after the beating, another onlooker yells: “This is f***ing Brick Lane”.

A waiter at the Eastern Eye Balti House - outside which the third man was attacked - said he did not know what triggered the incident.

The man, who asked not to be named, told the Standard: “It was closing time so I came out and there was police and ambulance there already.

“Obviously it came to our restaurant but it started somewhere else. I don’t know what happened.

“We gave the guy blankets from the restaurant because he had no clothes to cover him.

“He was talking, we were talking to him asking if he was alright, and neighbouring restaurants came with blankets too. You have to help someone if they’re lying down like that.”

He added: “People were walking around, it’s a busy place. Then police came and they were walking around looking for clues, but no one was arrested.”

A Metropolitan Police spokesman confirmed an investigation had been launched after officers were called to reports of a group of males fighting at around 9.45pm on Monday.

He added: “Officers from Tower Hamlets Borough attended and found a man, believed aged 36, injured. He was taken to hospital. His injuries were not life threatening and he has subsequently been discharged.

“No other victims were at the scene, but officers believe there could be two outstanding.

“Officers from Tower Hamlets CID are investigating and are keeping an open mind regarding any motive.

“There have been no arrests and enquiries are ongoing.”
