A 60-year-old man has been stabbed to death in a residential street in south London.
Police and ambulance crews were called to reports of a stabbing in Woodcroft Road, Thornton Heath, Croydon, at 21:30 GMT on Monday.
The victim was found outside a property with knife injuries and was pronounced dead at 21:49, the Met Police said.
A 50-year-old man was arrested at the scene on suspicion of murder and taken into custody.
The suspect became unwell while in custody and was transferred to hospital where he is in a stable condition, police said.
Det Ch Insp Simon Harding said: “The victim was found injured in a residential street. While it is not a heavy footfall location, there may have been members of the public travelling through Woodcroft Road who saw something.
“I urge those people to come forward and speak to my officers without delay.
“No matter how insignificant you think it may be please do make the call.
“We are building the sequence of events leading up to and immediately following this attack which has led to a man’s death, your call could complete the picture.”
Inquiries into the circumstances continue.
A homeless man who camped outside pop star Harry Styles’ house for several months has been found guilty of stalking the singer.
Mr Styles, 25, offered to buy Pablo Tarazaga-Orero, 26, food after he saw him sleeping rough outside his north west London home in March.
Speaking at Hendon Magistrates’ Court, the singer said he locks his bedroom door every night after being followed.
Mr Styles said the man’s behaviour was “erratic and frightening”.
The former One Direction singer said he was “sad to see someone so young sleeping rough” when he first saw Tarazaga-Orero.
He bought him vegan sandwiches, salads and muffins, after the rough sleeper asked for some edamame beans.
After trying to cut contact, the pop star saw him nearly every day, and received notes and money in his letterbox, District Judge Nigel Deane heard.
When asked whether he had stalked the celebrity, Tarazaga-Orero said: “That was never my intention. In the end I just wanted the money he offered me.
“I don’t have any feelings for him. I’m not in love with him.”
Tarazaga-Orero will be sentenced on 21 October.
