The family of a volunteer taxi driver shot dead on Koh Samui has sought witness protection from the Ministry of Justice.
Relatives of Sikkharin Phromcharoen, 31, fled Surat Thani with more than 10 family members, claiming they feared retaliation from influential local groups allegedly linked to the attack.
Sikkharin, known on Koh Samui for providing free transport to pregnant women, elderly residents, disabled people and poor families, was beaten and shot dead on May 24 in an alleged dispute involving illegal black-plate taxi drivers.
