Authorities in the northern province of Hai Duong on Friday said they are investigating a very unusual case in which a local man, who was serving his jail term, ended up being found dead in his own home.
According to local media reports, police could not explain how Nguyen Van Dinh was not inside his cell.
Dinh, 44, was serving an eight-month sentence for gambling that will end in July.
His relatives found his body on Tuesday morning on the second floor of the house, dozens of kilometers away from the jail.
Investigators said he had apparently hanged himself. But how he was out of jail remains a question they are still trying to decipher.
