South Wales Police on Friday identified a man found dead in the Cynon Valley as 41-year-old Vietnamese national Tinh Van Tran.
Tran’s body was discovered on Tuesday off a road in Abercynon, near Whitehall Golf Club.
The police has confirmed his identity in the hope it will lead to Tran's family coming forward.
The exact cause of his death is still unknown and forensic tests are being carried out, police said.
The WalesOnline website quoted local police as saying that Tran “may well have had links to the surrounding area.”
The police have also appealed for the occupants of four cars seen in the area on the day the body was discovered to come forward.
