A 'gentleman car park attendant' was attacked by a yob with a knuckleduster in a row over £3 for parking.
Mudathir Mohammed was knocked out with just one punch after he was brutally assaulted by the thug at a car park in Manchester.
The 28-year-old suffered a broken nose and needed four stitches to his lips.
Two men are seen approaching Mudathir before they lean closer in a threatening manner.
One of the men then swings a knock-out punch at his head.
The horrific assault was caught on CCTV before the two men run off to cars - a silver Audi and a black BMW - as Mudathir is left lying on the ground in agony.
He then gets on all fours, hauls himself up, and staggers to a gate, helpless, confused and covered in blood.
