A man has been arrested on suspicion of murdering a man who was stabbed to death outside a McDonald’s.
Peter Petrou, 37, was found dead in Kilburn High Road in north-west London at about 22:30 BST on Thursday.
His sister Emma said the family was “deeply devastated” by his death which came three decades after their sister Tracey Meade was murdered.
Scotland Yard said a 23-year-old man arrested on Tuesday on suspicion of Mr Petrou’s murder remains in custody.
“Peter was much loved by his large family and many friends,” Emma said.
“He was the life and soul of everything and the void he has left will be hard to fill.”
Tracey, 14, was found murdered in the Grand Union Canal two weeks after she went missing from her west London home in 1992.
She drowned after being stabbed. No-one has been convicted of her murder.
