A young man has been knifed to death in the third fatal stabbing in London in just 24 hours.
Police say a 20-year-old was stabbed in Wager Street, Mile End, at around 4.45pm on Tuesday.
He was rushed to hospital by paramedics but died around an hour later from his injuries.
Witnesses said the victim had been stabbed near his home and collapsed in the street.
Family members and neighbours ran out to help the young man as he lay in the road, it is claimed.
One witness told the Standard people were desperately trying to give the victim mouth-to-mouth in a bid to save his life before emergency services arrived on the scene.
Detectives believe the man was with friends in Wager Street before he was approached by a group of men and stabbed.
Police have arrested an 18-year-old man on suspicion of murder. He is currently being quizzed by detectives at an east London police station.
The news came after 19-year-old Abdullahi Tarabi was stabbed to death in Northolt an hour earlier at 3.30pm on Tuesday and another young man was killed in Plumstead on Monday.

Witnesses said Mr Tarabi was chased through an estate and cried for help before his brother tried dragging him to the safety of a nearby house in Newnham Close.
He was pronounced dead just after 5.30pm.
