A 21-second video clip of the incident, which went viral on Facebook yesterday, showed the driver of a car confronting the van driver, pulling him out and beating him, and standing menacingly over him as the van driver lay on the road.

The assailant can be heard saying, “Do you want more? Do you want more”, Harian Metro quoted Serdang police chief AA Anbalagan as saying in a statement yesterday.

He said police had yet to ascertain the motive behind the incident as none of the men had filed a police report.

He urged the two men as well as members of the public with information to assist the police in their investigation.

They may contact the investigating officer, Insp Sophian Sian, at 016-5092654, or the department’s operations room at 03-80742222.
