The incident, which went viral after people around there recorded the video was shared on social media, occurred at around 12:19pm near a 7-Eleven convenience store in the Baan Lipon area, Srisoonthorn.
The victim, Kengpong Nuansri, 38, a tool salesman, was reportedly assaulted after the taxi driver rear-ended his car.
According to the police report filed at 12:20pm, Mr Kengpong had parked his car to make a purchase at the store when the ’green-plate’ taxi driven by Sathaporn Suwanmanee crashed into him.
Sathaporn allegedly exited his vehicle, armed with a golf club, and proceeded to strike Mr Kengpong, causing injuries, before fleeing the scene.
Thalang Police were able to locate and arrest Sathaporn at 2:50pm at his residence in Moo 6, Srisoonthorn.
During questioning, Sathaporn confessed to drinking alcohol prior to the incident, said police.
He was subsequently taken to Thalang Police Station, where a breathalyser test confirmed his intoxication level.
Eyewitness Ms Fon said she saw the taxi driver, who was driving an Isuzu, hit the black sedan first, then get out and attack with a golf club.
She noted that the altercation lasted about 10 minutes, but she could not clearly see what led to the escalation due to other vehicles blocking her view.
Police have initially charged Sathaporn with driving under the influence of alcohol, causing bodily harm while intoxicated, and physical assault.
Thalang Police have submitted a report to the Commander of the Phuket Provincial Police for further action.
According to the police report, Sathaporn is currently in custody and awaiting further legal proceedings.
