Two men dead in another night of London bloodshed: Victim in twenties is stabbed after man in his fifties dies in fight at bookies

Two men have died in another night of bloodshed in the capital and police have now launched their 52nd murder probe of the year.
A victim in his 20s was killed after being stabbed in Hackney, east London, just hours after a man in his 50s died following a fight outside a bookmakers in nearby Clapton.
Officers were called at 4.27pm to the Betfred store after receiving reports of a man who was unconscious in the street.
He was involved in an 'altercation' with another man who left the scene and no arrests have been made.
And on Wednesday evening, police were driving in Hackney when they saw a young man had been stabbed and he died 30 minutes later.
It comes after a 17-year-old girl and 16-year-old boy were killed following a postcode war which has gripped London. 
Tanesha Melbourne was outside the home of her boyfriend's mother when she was shot on Monday evening in Tottenham, north London. 
The teenager became the 48th person to be murdered in London this year, after getting caught up in a terrifying postcode war ravaging the streets of the capital.
Also on Monday night, 16-year-old Amaan Shakoor, became the 49th victim of the continuing bloodshed after he was shot in the face in Walthamstow by 'rival drug dealers', according to a friend.
By Wednesday morning, the Metropolitan Police had launched 50 murder investigations - 12 in January, 15 in February, 19 in March and four in April.
