Thalang Police Deputy Chief Lt Col Suchart Luecha, on duty at the time, was informed of the incident at 8:15pm.
Police on patrol in Pa Khlok were informed via the 191 Incident Call Center and arrived at the scene, near the entrance to the Baan Suan Yu Charoen 5 housing estate on the main road, some 2.3km east of the Heroines Monument, to find the morbike still on fire.
Officers were unable to determine the make and model of the motorbike, but could tell from the license plate that it was registered in Phuket, police reported.
Local residents rushed to try to extinguish the fire, but a fuel explosion kept them at a distance while they tried to douse the flames. In the end, the motorbike was destroyed by the fire.
The man riding the motorbike at the time, who police did not name in their initial report, received first aid from rescue workers with the Pa Khlok Municipality Rescue Unit who had arrived before he was taken to Thalang Hospital.
Lt Col Suchart said that from their initial investigation police believe that a fuel line leak had caused the fire, but officers were continuing their investigation.
