Three men have been stabbed to death in London in little over 12 hours.
A man in his 20s was attacked in Hackney, east London, on Thursday afternoon. A 14-year-old boy and a 26-year-old man have been arrested.
Overnight, a man was found fatally wounded near Harrods in Knightsbridge, while another victim was killed in Deptford, south-east London.
The deaths mean 136 murder investigations have been launched in the capital this year.
It is the same amount as during the whole of 2018.
The victim who was killed in Knightsbridge was found unconscious near to luxury department store Harrods just after midnight after police had been called over reports of a stabbing.
He was treated by paramedics but pronounced dead at the scene at 00:39 GMT.
Another man was found injured and taken to hospital “in a serious condition”, police said.
Harrods said the store was open as usual but some entrances into the building had been closed due to the police cordon.
Emergency services were also called to Bronze Street, Deptford, at 03:00 GMT after a man was fatally stabbed.
No arrests have been made over either of the killings overnight and the Met have appealed for witnesses.
Detectives believe the victim killed in Clarence Mews, Hackney, on Thursday died following “an altercation involving a group of people”.
The two people arrested on suspicion of murder remain in custody but the Met said “at least two other suspects remain outstanding” and inquiries to locate them are “ongoing”.
