On Sunday, the 30-year-old Singaporean woman, whose name has not been revealed, filed a report with the local police, accusing a man, only identified as the manager of the guesthouse where she was staying, of raping her on Saturday night, local media reports said.

The woman, who was in the popular resort town of Phan Thiet in Binh Thuan Province on vacation, said she and her friend went out with the guesthouse manager for dinner and stayed out until late at night. After she returned to her room, he came at 1 a.m. and raped her, she said.

Following her complaint, officers summoned the 26-year-old manager for questioning.

The man denied the charge and said they had consensual sex. However, police said the woman’s body bore signs of sexual assault and that they are continuing the investigation.

In Vietnam, punishment for convicted rapists ranges from two years in jail to death sentence, depending on the seriousness of the attack and damage caused to the victim.
