Officers were called to Nicky’s Handlebar Hotel on 200 Pi Rath-U-Thit Rd at 8pm to find the body of the 65-year-old man lying on the bed in his room.
The man was identified by his passport, but his name is being withheld until it has been confirmed that his family has been notified.
Medical staff at the scene estimated that the man died between 12 and 24 hours before his body was found.
Maj Theerasak Boonsang of the Kathu police told The Phuket News that the man checked into the hotel on Tuesday (June 16) and was due to check out next Thursday (June 25).
“The room looked tidy, and we found no signs of foul play or assault,” Maj Theerasak said.
“We found prescription medicines in the room, and we believe the cause of death was related to a pre-existing medical condition of the victim.
“However, we are waiting for doctors at Patong hospital to confirm the cause of death.”
The Australian embassy has been notified of the incident.
