Tha Chatchai Police Station reported that the incident occurred at about 9:40am, inside a cream-coloured 60-foot Azimut yacht docked at the marina. Police reported they were called to the marina at about 9:50am.
The injured man was identified as ‘Win Mo’, a Myanmar national. He suffered stab wounds to the abdomen and was found receiving first aid from Mai Khao paramedics when officers arrived at the scene. He was later transported to Thalang Hospital. His condition was described as serious.
The suspect, identified as Myat Phone Kyaw, also a Myanmar national, was found waiting at the boat berth and surrendered to police without resistance.
According to an initial police investigation, the suspect told officers that he and the victim had been drinking alcohol together on the boat prior to the incident. An argument reportedly broke out, escalating into a physical altercation during which a knife was used.
