Brawl at rail station linked to later knife murder: Met
The murder of a man who was stabbed to death may have been fuelled by a rush hour brawl outside a busy railway station, police said.
Scotland Yard said the stabbing in north-west London on Thursday night and the fight earlier that day outside South Hampstead station bore the "hallmarks of gang violence".
The investigation is also being linked to an injured man being found about 15 minutes after the murder victim was discovered, the force said.
Five men have been arrested and police are appealing for witnesses to all three incidents.
Detective Chief Inspector Simon Stancombe, who is leading the investigation, said the brawl may have "fuelled" the later stabbing at Ainsworth House.
He added: "We are keeping an open mind about motive but both the murder and the incident at South Hampstead station bear the hallmarks of gang violence.
"We believe the earlier altercation may have fuelled the later incident which has led to a man losing his life."
