A policeman in the southern Vietnamese province of Binh Duong was found dead inside his house in Thuan An District on Saturday.
Captain Nguyen Van Dung, deputy head of Di An District police department's criminal police section, was found handing by a rope at 8 p.m. on Saturday after relatives came to his room calling him to come and eat.
The 33-year-old policeman was going to get married, neighbors said, adding he had sent wedding invitation cards to his relatives and friends several days ago.
Preliminary investigations showed that Dung died of suffocation caused by the rope, Binh Duong police said Sunday.
It was likely that the policeman committed suicide because of personal affairs, they said.
Police are investigating the death.
