Detectives continue to investigate a fatal stabbing in Barnet on Bank Holiday Monday.

Officers were called at 17:54hrs on Monday, 31 May to Montrose Park, Edgware, following reports of a group of males fighting.

Officers responded and found an 18-year-old male suffering from a stab injury in a tennis court area.

He was treated by London’s Air Ambulance and London Ambulance Service at the scene. Despite their best efforts, he was pronounced dead at 19:19hrs.
