COLLAPSED on the floor of the Brentford High Street McDonalds, a 19-year-old man suffering stab wounds was found to be in possession of a prohibited Tazer gun.

Shocked customers looked on as a traffic PC, who was already in the restaurant, called for help soon after the youth entered the fast food restaurant, on Monday at 12.30pm - rush hour.

An air ambulance was called to the scene but was not used, and the youth was taken to West Middlesex Hospital on Twickenham Road, Isleworth.

Police found him in possession of a Taser stun gun - a section 1 prohibited weapon under the firearms act, which discharges an electrical pulse and is in use by the police. The youth told police that he had taken it from his assaulters.

The restaurant had to be closed for two hours, as the car park was sealed off and examined for evidence.

Police are looking for two black men, one of which is described as 17-years-old, in connection with the attack. Anyone with information should call 020 8247 6118.

The youth recovered from his injuries and was discharged from the hospital later that day.
