A man has surrendered to police to face a charge of murdering a passenger in his mother's car, who was chased down by a motorcyclist and shot dead in Kanchanaburi on Monday.
Relatives accompanied Sitthichai Mankhong, 29, a local government employee, to surrender to police.
The victim, Ampol Bungthong, 27, was shot 10 times, in the head and body, with a 9mm pistol, police said.
Ampol was a passenger in a pickup truck driven by Rojana Cheewee, 50. A motoryclist confronted the pickup and driver when it stopped at an intersection about 8.20am.
Ampol ran from the pickup, chased by the man on the motorcycle, to the car park of a shopping mall. There, the motoryclist shot him dead, firing repeatedly at him. A surveillance camera recorded the gunman shooting the victim.
Mr Sitthichai is Ms Rojana's son.
He faces a charge of murder.
