Police in Phu Tho Province on Thursday arrested a teacher after his 15-year-old student accused him of raping her.
The girl's father told the police that his daughter seemed panicked after returning from a visit to her teacher, Le Minh Son, for a study session on November 23.
The girl said that the teacher had raped her at his house.
Son denied the allegations,at first. However, police say he admitted to the crime after the family filed a formal accusation with the authorities.
The 56-year-old said he couldn't contain himself. He's had to restrain his sex life recently due to his wife's bout with cervical cancer, Son said.
Raping minors in Vietnam can carry either a life sentence or the death penalty, according to the Penal Code.
