Police in the north central province of Thanh Hoa Monday arrested a teenager for allegedly raping and drowning a teenage girl to death in a river.
Le Tuan Anh, 17, confessed to the killing of Nguyen Thi Bich Ngoc, 17, two days earlier.
He told the police he had met Ngoc in a village in Quang Xuong District the same day, became friendly, and asked her to go to the Tinh River where he forcibly raped her.
Then he tied her hands and held her head under water until she died.
At around 6:30 p.m. the next day a group of children playing by the river bank discovered Ngoc's naked body floating in the water with her hands tied together with a bra.
Local residents told police they saw a boy swimming across the river on the evening of August 11. He had then gone to a local house and asked to borrow dry clothes and money, they said.
Based on their tipoff, police summoned Anh who was reportedly absent from home since August 11, and he confessed to his crime.
They said he did not act anxious at all during the questioning. He had even said calmly: "I am a relative of Le Van Luyen, so I had to do something like he did."
Le Van Luyen is a teenager who achieved notoriety for killing a couple and their daughter to rob gold from their shop in Bac Giang Province last August.
He escaped the death penalty since he was two months shy of his 18th birthday when he committed the crime. For criminals below 18 the maximum penalty under Vietnamese law is 18 years in jail.
The case sparked public outrage, with many calling on legislators to change the law to prevent minors from committing brutal murders.
