A teenager was held at Taser-point near to Hampstead Heath after reports a rail worker was threatened with a knife.

Images seen by the Ham&High show an officer pointing the taser at a young male near the M&S Foodhall in Pond Street on Sunday (April 2).

Metropolitan Police says that officers arrested a boy on suspicion of possessing an offensive weapon.

The case was then passed on to British Transport Police.

A spokesperson for the force said two boys, 15 and 16, were arrested on suspicion of possessing an offensive weapon.

They have been released on bail, pending further enquiries.
