Crime campaigners fear gang warfare is spilling onto the leafy streets of Hampstead and Belsize Park after two shootings and a knife attack this month.

They have called for police action before “someone gets caught in the crossfire.”

Detectives are hunting a gunman after a 20-year-old man was shot in Fellows Road last Wednesday night.

Police were were called at around 11.20pm to reports of gunfire.

They found evidence of a gun having been fired and were later told that a man had been treated in hospital for a non life-threatening gunshot injury.

This comes after two carjackings outside Tinseltown restaurant in Heath Street where shots were fired.

As reported in the Ham&High in the first on September 2 two male victims in their mid-20s reported that there had been an unsuccessful attempt to steal the car that they were driving in during which shots were fired.

The next night there was another carjacking where victims reported they were threatened with a gun and a knife.

In a third incident being investigted by Trident detectives two men were stabbed in Eton College Road after being attacked by a gang at around 11pm on September 15.

Cordons were set up around a mansion block and South Hampstead synagogue following the incident. The suspects,described as a group of up to six black men wearing balaclavas, fled the scene in a dark coloured Mercedes 4x4 and a light coloured Mercedes coupé.

Jessica Learmond-Criqui, who chairs the Frognal and Fitzjohns Safer Neighbourhood panel said: “Something is going on here. It appears that gangs have moved up here and there is a risk of residents being caught in cross-fire.

“We want to know what the police are doing about it and why these kind of criminals are coming here.”

Detectives from Detectives from the Trident and Area Crime Command are investigating all the incidents.
