Police in the Mekong Delta city of Can Tho have arrested a 23-year-old man for allegedly raping an 80-year-old woman in her house.

Nguyen Van Tat reportedly snuck into the house of his neighbor Nguyen Thi T. while she was lying on a hammock inside on the evening of February 19.

Tat covered T.’s face with a shirt and pulled her into a room, police said.

As she struggled, Tat strangled her and weighed down on her chest until she passed out, according to investigators.

After raping her, T left the house. T.’s grandson spotted him and then figured out what happened.

T. was rushed to hospital while her neighbors called local police.

T. was arrested on February 26 while hiding in a paddy field.
