Patong Police were called to the scene, in front of the Novotel Phuket Vintage Park Resort on Rat-U-Thit 200 Pi Rd, at about 6:45am.
Officers arrived to learn that the drivers, Apinan Bunpa, 40, and Rapeepan Sae-Lor, 55, had been involved in an argument that turned violent.
According to witnesses and initial police investigations, the two men had previously been engaged in a heated online exchange within their taxi group.
The dispute revolved around accusations of stealing customers and inappropriate conduct within the taxi queue.
The argument culminated yesterday morning when the two drivers encountered each other in person at the taxi queue outside the hotel.
During the confrontation, Rapeepan drew a knife, some 27cm long, wrapped in a blue cloth, and stabbed Mr Apinan once in the abdomen.
Both men were quickly taken to Patong Hospital for treatment. Mr Apinan’s stan wound was not described as serious.
Speaking to police from his hospital bed, Mr Apinan recounted the incident. He claimed that the argument began after he confronted Rapeepan about previous comments made in their online group chat.
Mr Apinan, who is relatively new to the taxi queue, stated that he was unfamiliar with the specific rules and regulations of being a member of the group, which may have contributed to the misunderstanding.
CCTV footage from the scene showed Mr Apinan parking his Isuzu vehicle behind Mr Rapeepan’s red car before approaching and appearing to initiate a physical confrontation.
Moments later, Rapeepan is seen pulling out a knife and stabbing Mr Apinan.
Police said they were continuing their investigation into the incident, with charges expected to be filed.
