Mrs Suthira later saw the video clip and felt that Mr Akanat's actions were unacceptable, so she took her son to the police station to file a complaint.
Mr Akanat and his lawyer on Sunday night went to see the police station, and were there for about three hours.
The lawyer, Adul Tinapong, said his client reported a hit-and-run accident that left his car damaged. He said Mr Akanat had punched the motorcyclist in an act of self-defence.
