British police have released dramatic footage of the arrest of a drunken gunman who was caught on CCTV as he fired a shot at a crowded pub.

N-Dubz rapper Dappy sparked a “mob attack” at a petrol station when he spat at two girls who refused to get into a car with him and two friends, a British court has heard.

N-Dubz star Dappy will stand trial over a fight at a petrol station which left three men with serious facial injuries, court staff said.
