A young man has been knifed to death in the third fatal stabbing in London in just 24 hours.
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.
He said: “Many people were trying to help, shouting and crying.”
Another neighbour said: “All we heard was a lot of screaming and then a car sped off with tyres screeching.”
Footage published on social media showed a group of residents and distressed family members desperately trying to help the stricken man as he lay on the ground beside a car.
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.
Detective Chief Inspector Tony Lynes, from the Met’s Homicide and Major Crime Command, said: “We are keen to speak to anyone who was in the area at that time and might have seen what happened or who has any information about the circumstances.”
Mayor of Tower Hamlets John Biggs tweeted on Wednesday morning: “Extremely saddened by fatal stabbing in Mile End last night.
“Have met victim’s family to offer deepest condolences and extend council’s support.”
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.
The stabbings came in Cressida Dick’s first week as the Met’s new Commissioner, highlighting the challenges she faces in reducing knife crime in the capital.
