The clip shows the naked couple engaging in sex in the open cargo bed of a black pickup truck travelling northbound along the bypass road in Rassada.
A local resident filmed the scene before sharing it online, where it quickly spread across Thai social media platforms late last night.
Online outrage erupted within hours of the video being posted. Comments condemned the act as “shameless”, “disgusting” and “disrespectful to Thailand”, with some users calling for the couple to be deported. Others criticised the behaviour as a dangerous distraction for motorists and a stain on Phuket’s reputation as a tourist destination.
Phuket City Police confirmed that they are investigating the incident and are reviewing CCTV footage along the route to identify the vehicle and the people involved
Police have not yet confirmed the time the video was recorded or whether the couple are tourists or residents.
Public indecency is a criminal offence in Thailand, carrying penalties that may include fines, arrest and deportation for foreign nationals. Police have urged anyone with information about the vehicle or the couple to contact Phuket City Police Station.
