According to Kamala Police, a lifeguard told the police that he saw the tourist, identified as Piotr Dawid Rudnik, arrive at the beach around 8am.
The incident began when lifeguards spotted the man floating face down in the water at around 10.35am.
They immediately pulled him from the water and began performing CPR.
A rescue team from Kamala Tambon Administrative Organisation (OrBorTor) responded shortly after. CPR continued during the transfer to Patong Hospital.
Despite these efforts, Mr Rudnik was later pronounced dead at Patong Hospital.
Patong Hospital confirmed that drowning was the cause of death. No signs of physical assault or foul play were found, and the man’s friends and family have not expressed any other suspicion over the circumstances.
