Squad cops held a woman in her twenties after a man was stabbed to death at a flat he shared with his young daughter.

Shocked neighbours say a young girl was led away by police in a blanket after paramedics desperately tried to save the victim's life in London's East End.

The man, who also had a dog, lived on the seventh floor of a block of flats on the Isle of Dogs with a woman and his daughter, according to local residents.

One, Charley Knight, said on Facebook: "I saw the mum come out and the police were wrapping something round her hands and then put the silver blanket thing round her, then dad was brought out in handcuffs and then later their little girl in a blanket.

"Whatever happened it's sad a little girl saw/heard it all."

Tracey Fisher posted: "My husband see a woman in handcuffs and some children with blankets around them and 4 paramedics came out a well."

A woman in her 20s was arrested on suspicion of murder and police have confirmed they are not looking for any one else in connection with the killing.

A London Ambulance Service spokesperson said: "We sent a motorcycle responder, an incident response officer and an ambulance crew. We also dispatched London's Air Ambulance by car.

"Sadly, despite extensive efforts, a person was dead at the scene," said a London Ambulance Service spokesman."
