Phuket City Police confirmed that the fatal crash occurred at about 12:07pm at the intersection of Bangkok Rd and Poonphol Rd in Phuket Town.
The victim was identified as a French national. He was critically injured while walking on the sidewalk and later pronounced dead at Vachira Phuket Hospital at about 3:30pm.
Police said the driver, Jatuphol Kerdpol, 51, from Phang Nga province, was driving a grey Volvo when he lost control and collided with a series of vehicles.
Initial investigations found that the suspect first crashed into several cars and motorcycles in front of the Government Savings Bank on Bangkok Rd before fleeing the area.
The vehicle then continued to the Bangkok-Poonphol intersection, where it struck the Frenchman and two motorcycles, police said.
In total, nine vehicles, including cars and motorcycles, were damaged during the rampage.
Both the suspect and the victim were rushed to Vachira Phuket Hospital by rescue workers. Police later conducted a breath and blood alcohol test on Mr Jatuphol, which confirmed his blood alcohol level was above the legal limit, officers said.
Phuket City Police have charged Mr Jatuphol with driving under the influence causing death and property damage, and fleeing the scene without taking responsibility. The vehicle involved has been seized for forensic examination as part of the investigation.
Phuket City Police Superintendent Pol Col Chatree Chukaew confirmed the incident and said investigators are proceeding with all relevant legal steps. The case is being handled by Pol Lt Surachach Saenchon, Deputy Inspector (Investigation) at Phuket City Police Station.
