The body was discovered by a passer-by early this morning (Mar 29).
Phuket City Police were called to the park at about 3:30am.
Joining police at the scene were forensic specialists from Vachira Phuket Hospital rescue workers from the Kusoldharm Phuket Foundation.
Rescue workers retrieved the body, which was floating face down. The deceased was identified as a male, estimated to be between 40 and 50 years old, but his identity and nationality remain unknown.
He was wearing a black short-sleeved shirt with orange and yellow patterns, black shorts and a black leather belt.
Notably, two iron dumbbells, each weighing approximately five kilogrammes, were tucked under his belt at the front of his waist.
A pair of black flip-flops was discovered on the riverbank nearby.
A preliminary medical examination indicated that the man had been dead for about three days, police said.
No identification documents, wounds or signs of physical assault were found on the body, and the initial cause of death could not be determined.
The body was taken to Vachira Phuket Hospital for further examination. Meanwhile, investigators from Phuket City Police are reviewing CCTV footage from the surrounding area in an effort to establish the man’s identity and determine the circumstances leading to his death.
