The main suspect, 33-year-old Somporn Kakkaew, confessed to police that the stabbing took place because he believed he was going to lose a fight with the two tourists, named as French national Akim Boukheddouma, 24, (the deceased) and 23-year-old Moroccan, Said Missoury.
Lt Col Suthichai Tienpo from Kathu Police, together with tourist police, investigated the incident and after checking CCTV footage from the area discovered that Somporn had an accomplice who joined the fight just before the stabbing took place.
The investigation led to the arrest of 30-year-old Somkit Lemut, who police learned worked at the same pub in Soi Sansabai as Somporn.
Somkit told police that while he was inside the pub getting ready to close, he noticed Somporn arguing and fighting with two tourists outside.
He went to help Somporn after seeing him being attacked, when suddenly Somporn pulled out a knife and stabbed one of the men.
He also told police that the tourist attempted to take the knife from Somporn which resulted in both Somporn and the tourist sustaining knife wounds.
“The two tourists ran towards a hotel about 200 metres from where the incident took place. I took Somporn to hospital and on the way dumped our bloody clothes in a rubbish bin on Taweewong Rd,” Somkit told police.
Lt Col Suthichai explained: “I went to Vachira Hospital after learning that Somporn had been admitted there for a knife wound to his wrist. I was told that he had lost a lot of blood because the wound was on the main artery so we had officers monitor him while he received treatment.
“Somporn told us that he had just finished work and was heading home on his motorbike when two drunk tourists lurched into his bike. They accused him of driving his motorbike into them before an argument ensued, which escalated into a fight,” he said.
Somporn told police: “Even though Somkit came to help me, I realised I was not going to win the fight because both tourists were stronger than us so I decided to use the weapon.”
Lt Col Suthichai concluded, “Both men confessed and gave details of the incident, which matches the CCTV footage we obtained. We have all the evidence including the knife and key witnesses. Both men will be punished according to law.”
Somkit now faces a charge of accessory to assault causing death and injury, while Somporn will be charged with murder and assault causing death and injury.
