Apimon Sathornkij, 37, had come to the aid of another motorcyclist who’d upended in front of the Harley-Davidson service centre on Sukhumvit Road in Chon Buri’s Bang Lamung district when Oleg Volobujev, 45, allegedly ploughed into him.
Police said Volobujev, who had a Thai woman riding pillion, was speeding and was so drunk that all he could say was that he was indeed drunk.
He was taken to the police station and, once sober, would have to negotiate compensation for Apimon.
