The accident occurred at about 3:20am on Thepkrasattri Rd northbound, several hundred metres north of the Heroines Monument, said Capt Kraisorn Boonprasop of the Thalang Police.
Kusoldharm rescue workers recovered Snr Sgt Maj Rong Nuankhawn, 39, of the Tourist Police, from his mangled Toyota Vios and transported him to Vachira Phuket Hospital in Phuket Town for a head injury.
“We have yet to question the victim, but we believe he lost control of his vehicle on the wet road since it was raining hard in the area at the time of the accident,” said Capt Kraisorn.
The wrecked Toyota Vios was impounded as evidence and taken to Thalang Police Station, he added.
Capt Kraisorn made no mention of whether Snr Sgt Maj Rong would undergo any alcohol or drug tests, or face any charges for the accident.
