A 26-year-old man accused of killing a married father of three by knocking him to the ground in a supermarket car park, has been cleared of manslaughter.
Saqib Rafiq was alleged to have "lost his temper" with Manji Hirani, 48, in Queensbury, north London, last December.
The Old Bailey heard Mr Rafiq hit Mr Hirani after he had struck Mr Rafiq's windscreen with a bag of beer cans.
Mr Hirani suffered brain injuries and died two weeks later.
The court heard Mr Rafiq, of Carlton Avenue East, Wembley, north London, had been in his father's Audi with friends in the Morrison's car park in Honeypot Lane.
Mr Hirani, who had problems with alcohol, struck the rear windscreen of the car with his hand and a plastic bag containing beer cans.
Rafiq later admitted that he had struck the older man but said it was "a bit of silliness" and he had wanted to protect his father's car, the court heard.
