This is the terrifying moment a man shocked his two attackers by pulling out a 12-inch knife during a brawl at a train station.
CCTV captured two youths attacking a third person as they all come through the ticket barrier at Moor Street station in Birmingham city centre.
One of the men then falls to the floor and is dragged around by his foot before the second assailant runs towards him.
But the person on the ground suddenly unsheathes a 12-inch kitchen knife from under his black sweatshirt.
He waves the weapon towards his two attackers and chases after them as they quickly sprint away.
British Transport Police today released the shocking 23-second video in a bid to identify the three men involved in the fight on August 25 at about 7.15pm.
