London Stabbings: Murder Probe As Man Held

A man has been arrested on suspicion of murder after a woman was killed and two others - including her sister - suffered serious stab wounds.

The 40-year-old was detained overnight after officers were alerted to attacks at two separate south London flats on Monday evening.
A woman aged 28 and her 17-year-old sister were found with knife wounds at 7.10pm at an address in Tilson Gardens, Brixton.
Police said the teenager had suffered wounds to her head and hands as she tried to protect her sister.
The woman was pronounced dead at the scene, while the girl was taken to a south London hospital and is in a serious but stable condition, Scotland Yard said.
Half an hour earlier, another woman, aged 46, was found at a property in Redlands Way with a number of injuries, including stab wounds. Her condition is described as critical.
Young children were present at the scenes of both attacks and officers want to establish if they saw anything significant.
Forensic examinations were taking place at the two properties, which lie less than a mile apart.
Police said all three victims were known to the man being held in custody at a south London police station.
A woman who lives in Redlands Way said she came outside when she heard a woman screaming that someone was trying to kill her.
She said: "The woman had got out on to the balcony and she was just screaming. There was this tall, black guy who came out of nowhere - it was like a film.
"He just grabbed her and stabbed her in her back - a couple of us saw it. The children were playing out in the park right in front which made it more traumatic.
"People started calling the police and I was trying to get my daughter inside so I could go down to see whether I could do anything.
"The guy escaped but we saw her coming down with bandages and the bandages were bleeding."
It is understood an eight-year-old boy was in the bathroom of the Tilson Gardens property when the attack happened.
The suspect was arrested on a bus in Leigham Court Road, Streatham, south London, shortly before 1am.
Detective Inspector Will Reynolds said there was no suggestion it was a random attack and officers are not looking for anyone else.
