This is the shocking moment a balaclava-clad thug is mown down by a car as he hunts a rival with a machete-wielding gang in the middle of day before being left for dead by his accomplices.

The man in his 20s sustained serious head injuries after being thrown into the air and flung 50 feet along the pavement by the hit and run driver - who was apparently trying to save the man they were chasing.

His three accomplices tried to drag him into a waiting getaway car but gave up when he proved too heavy to lift and decided to save their own skins.

Footage filmed on a home CCTV camera shows a man in a black tracksuit sprinting along the road, apparently being pursued by three masked men in black wielding machetes and bats.

As the first three men disappear from frame, a blue car is seen racing towards a third man who has fallen behind.

The vehicle continues to accelerate and rams into him, crushing the man against a parked car and throwing him into the air.

The force of the impact sends him skidding about 50 feet along the concrete, ripping his trousers down in the process.

His accomplices stop and turn around as the blue car speeds away - allowing the first man to escape.

They rush to help the fallen man and try dragging him into a black getaway car but are unable to move him more than a few inches.

He and his accomplice appear to threaten the lone woman with weapons as she backs away in horror with her hands raised.

The getaway driver then hops out and the three men make a second attempt to pull the badly injured man into the car but they give up after just a few seconds.

They get back in the vehicle and flee, leaving their partner in crime unconscious at the side of the road as the witness urgently dials 999.
