Heroic members of the public managed to stop a man making off with a bag of cash he had stolen from a nearby post office.

The man, believed to be in his 20s, was brought down by passers-by in Northolt Road, South Harrow, having held up the post office with a fake gun on January 27.

Police, who were called to the scene at around 1.20pm, confirmed that the suspect had walked into the building with the ‘gun’ in his waistband before waving it at a member of staff.

He then jumped over the counter, filled up a bag with money and ran out the front door.

But he was stopped in his tracks by members of the public, who held him until the police arrived.

He was arrested and taken to a West London police station while another man was treated in hospital for minor injuries.
