A Thai drug dealer has been found to be involved in the death of a boy who was attacked and killed in Khon Kaen last week.
The Immigration Bureau has reported that the boy, 17, was attacked at a school football field.
Police have arrested some suspects they believe to have been involved in the killing.
On January 20, a video clip of the attack was shared on social media.
The suspects have already confessed that a Facebook user named “Thep Solo” had hired them, police said.
The teenager was apparently killed as he had not paid for recent drug purchases, they added. Police have already identified “Thep Solo” and the drug network for further investigation.
