Patong Hospital alerted Maj Theerasak Boonsang of the Patong Police to the shooting at 3:41am.
The victim, Sayan Padungsap, 35, sustained four gunshot wounds: to his abdomen (left side), hip (back right), left foot and lower left leg.
Mr Sayan told police that Thanaphol shot him then fled the scene, leaving his vehicle behind at the parking lot, reported Maj Theerasak.
“Witnesses said that both men knew each other and they were having an argument which resulted in the shooting,” he said.
“We theorise that Sayan and Thanaphol met at the car park to settle some issue, but the negotiations went wrong and resulted with the suspect shooting Sayan four times,” he added.
“We are seeking a warrant of arrest for Mr Thanaphol now,” Maj Teerasak said.
Sayan was later transferred to Vachira Phuket Hospital in Phuket Town.
