Mr Chuan and other family members were resting in the house at the time. No bullets hit the house.
Trang police said the incident was reported on Thursday morning by Meechai Charoenwong, a lecture at Trang Vocational College and Mr Chuan’s close aide. Mr Meechai also handed over to police seven spent 9mm bullet cartridges collected from the street in front of Mr Chuan’s house.
Pol Lt Col Sarawut Chongcharoen, deputy superintendent and head of Trang’s forensic division, led a team to inspect the scene. The police found another two spent shells.
Kit Leekpai, president of the Provincial Administration Organisation who stays at the same house, told the police that he heard the sound of gunshots, or maybe firecrackers, at about 11.40pm on Wednesday but was not concerned because similar noises were heard earlier during a fight between some teenagers.
Police said the shells were found next to the fence and there was no damage to the house. They thought the shots were fired up into the sky.
Pol Maj Gen Jeerawat Charoensud, commander of Trang police, said there was no possibility of collecting DNA samples from the cartridge cases because local residents had also touched them in the street. Police will review closed-circuit camera footage to see if they can identify those responsible.
Pol Maj Gen Jeerawat said a special police guard had been assigned to take care of residences of local politicians after the Trang house of Sathit Wongnongtoey, a core leader of the anti-government protest, was hit by gunfire recently.
