A man threatened to kill another driver and waved around a massive knife in a video showing a terrifying road road chase.
Filmed by the knifeman, the footage showed him and a driver hurling vile abuse at the occupants of a blue Audi S3 in front.
The passenger can be heard repeatedly telling the driver to pull over before threatening to kill its occupants.
He can be heard shouting: "Pull up blud, pull up blud, ah you're dead.
"Where you going, the police station?"
The car in front is driven faster to get away from the vehicle following.
And in a desperate bid to escape, the car swerves across hatched markings on the road and overtakes another car in Birmingham, according to the Birmingham Mail.
