A petty road altercation turned into a vicious assault when a French driver was beaten up for not starting quickly enough at a green light in Fontainebleau, south east of Paris.
The attack took place in the late afternoon on June 29th after the victim, a tradesman in his forties, couldn't restart his Renault van immediately at a green light because of a clutch problem.
The Mercedes van driver behind impatiently honked his horn and the victim got out to apologise, then managed to re-start, reported Le Parisien newspaper.
But a bit further on the Mercedes overtook the tradesman and came to a halt in front of his vehicle.
Three men got out, pulled the man from his vehicle and threw his keys and mobile phone onto the verge.
The trio then delivered a brutal volley of kicks and punches, with one of the attackers even wielding a baseball bat, according to reports.
Once they had gone, the victim managed to find his keys and drive to a hospital, where he then lost consciousness. He reported the incident to police two days later.
The man was left with facial, chest and abdominal injuries and has been granted 31 days of incapacity leave by doctors (jours d'incapacité totale de travail).
The police, meanwhile, have appealed for witnesses as the trio remain at large.
