The case relates to the death of 30-year-old Sikharin Promcharoen, who was killed in Bo Phut, Koh Samui, Surat Thani province, on 24 May 2026. Investigators from Bo Phut Police Station gathered evidence and obtained court warrants for a total of 12 suspects allegedly involved in the killing.
Police had previously arrested 11 suspects. On 1 June 2026, the final suspect, Thawatchai, surrendered to investigators at Sichon Police Station. He was formally charged with jointly committing murder, jointly possessing firearms and ammunition without permission, jointly carrying firearms in a town, village or public place without authorisation and without reasonable cause, and jointly discharging firearms using explosives without justification in a populated area.
Authorities said the suspect was transferred to investigators at Bo Phut Police Station for further legal proceedings. The investigation was led by officers from Surat Thani Provincial Police. Police Major General Suwat Suksri, commander of Surat Thani Provincial Police, received reports from all operational teams involved in the case. He praised investigators for their work in gathering evidence and locating the suspects within a short period of time.
The police commander instructed investigators and related officials to continue compiling evidence carefully and thoroughly as the case moves forward. He emphasised the importance of reliable forensic evidence and maintaining public confidence in the justice system.
The case has drawn attention due to its impact on public safety in one of Thailand’s best-known tourist destinations. Authorities said they are committed to ensuring that all legal procedures are conducted in accordance with the law and supported by strong evidence.
Thaitabloid reported that police will continue preparing the case for prosecution while further examining the evidence collected during the investigation. Authorities expect legal proceedings against all 12 suspects to continue through the judicial process.
Police Major General Suwat also instructed station commanders across the province to strengthen security measures in tourist areas. Officers have been told to engage regularly with local residents, listen to complaints and concerns, and closely monitor situations that could lead to conflict or affect public order and the area’s tourism image.
