A British national facing vehicular manslaughter charges in a fatal Koh Phangan motorcycle crash now faces four additional charges for allegedly operating a tour boat business through Thai nominees, according to Thai police.
The Fatal Collision
On May 23, British citizen Wilcock Paul Duncan, 51, struck Associate Professor Dr. Theerasak Kaew-Amornwong while riding a motorcycle on the road between Koh Phangan Hospital and Thong Sala district. Dr. Theerasak, a 53-year-old respiratory medicine specialist and volunteer physician at the island's hospital, suffered catastrophic head trauma and died June 7 after 15 days in intensive care.
Police arrested Duncan the following day aboard a ferry as he attempted to leave the island. Following Dr. Theerasak's death, prosecutors charged Duncan with reckless driving causing death, which carries significantly harsher penalties under Thai criminal law, along with related charges including driving without a valid license, operating an unregistered vehicle, and lacking compulsory insurance.
Business Investigation Uncovers Four Additional Charges
During the expanded investigation, detectives from the Surat Thani Provincial Police uncovered evidence that Duncan allegedly operated Reef Charter Company Limited, a boat tour business on Koh Phangan, using a Thai national named Chamnong Rungrueang as a nominee shareholder.
Under questioning, Chamnong testified he worked only as an occasional boat driver for Duncan and never invested capital in the company. He stated he provided personal identification documents to Duncan under the belief they were needed for employment paperwork.
This testimony formed the basis for four additional criminal charges against Duncan:
• Providing false information to government officials in official documents
• Operating as a foreigner in a business reserved for Thai nationals (tour operations)
• Inducing a Thai national to assist or support a foreign-owned business without proper authorization
• Operating a tour business without required permits
Why This Matters
Nominee business structures under scrutiny: The case highlights enforcement of laws prohibiting foreigners from using Thai proxies to operate restricted businesses.
Multiple charges carry substantial penalties: Duncan now faces 11 separate criminal charges spanning from fatal reckless driving to document fraud.
Tourism sector enforcement intensifies: The prosecution signals tighter oversight of boat charter and tour companies across southern islands, where nominee arrangements have historically been common.
Thai Business Law and Foreign Operators
The Thailand Tourism Business and Guide Act of 2008 explicitly reserves tour operation licenses for Thai nationals and companies with majority Thai ownership. Foreigners may not circumvent these restrictions by registering Thai citizens as nominal shareholders while maintaining effective control and collecting profits.
Penalties for operating tour businesses without authorization include fines up to 500,000 baht, imprisonment up to two years, or both. Document fraud and nominee arrangement violations carry additional sentences.
The Thai government has intensified enforcement in popular tourist zones including Phuket, Krabi, Koh Samui, and Koh Phangan, with particular focus on boat charter operations, diving schools, and beach activity services.
Victim's Professional Standing
Dr. Theerasak held the rank of associate professor and specialized in respiratory critical care, making regular volunteer trips to provide medical services on Koh Phangan where healthcare resources remain limited. His death prompted an outpouring of grief from the medical community and island residents who had benefited from his volunteer work.
Case Proceedings Continue
The combined charges are expected to proceed through Thai courts. If convicted on all 11 counts, Duncan could face substantial prison sentences along with potential deportation and permanent entry bans. The case underscores the serious consequences Thailand pursues for traffic violations involving death or serious injury.
