Five people including four police officers were injured after cops were attacked by 100 youths outside Westfield shopping centre in Stratford.

Officers had been responding to reports of a robbery at Stratford bus station, which is next to the mall, when they were “met with hostility by a large crowd of people”.

Footage from the scene shows officers detaining a suspect before they are pursued by the huge crowd.

"Around 100 members of the public threw bottles and missiles at police," Scotland Yard said in a statement.

Four officers suffered minor injuries, while another woman was hurt after she fell down a flight of stairs during the disorder.

Three people were arrested, two on suspicion of being in possession of an offensive weapon and one on suspicion of robbery.

The Met's Taskforce Twitter account later posted a picture of a hunting knife it had recovered from the incident, which happened just before 8pm on Saturday.

Meanwhile, just half a mile away from the disorder, a man in his 40s was stabbed to death in the early hours of Monday.

Police were called to Whalebone Lane by paramedics at about 12.40am. The man was pronounced dead at the scene about 20 minutes later. No arrests have been made.
