CCTV footage shows a man being violently knocked over after attempting to stab a vehicle's tyre.

According to reports, the knife-wielding man had a run-in with the vehicle's owner, and was trying to exact a spot of revenge.

Clearly, though, it didn't work out for him. The footage shows the man casually walking up to the vehicle and trying to plunge the knife into the tyre's sidewall. But the force of the air escaping then knocks him over — ripping off his jacket in the process — and he lands face-first on a rather hard-looking set of steps. Ouch.
