Police in the southern province of Binh Duong are investigating the death of a 16-month-old boy who suffered brain trauma at a private nursery.
According to initial information, on September 8, Phan Van Loi brought his son to the home nursery of Nguyen Ngoc Anh, who agreed to babysit the child for VND1 million (US$48) per month.
Both Loi and Anh are renting houses in Thuan Giao Ward, and Anh lives just 30 meters away.
The next day Anh brought Nam, who was then unconscious, to Loi's house, police said.
Loi and his wife took Nam to the Binh Duong General Hospital, where he was found to have blood clots in his brain due to injuries and therefore was concluded to be in clinical death.
The boy died Thursday at the Ho Chi Minh City Children's Hospital No.1, where he was admitted on Sunday.
Anh told police that at around 6 p.m. on September 8, she locked her house from the outside to buy food, leaving Nam with her grandchild, reportedly four years old, inside.
When she got back an hour later, she found Nam lying on the floor, unconscious, so she brought him to the bed and returned him to his parents the next day, she added.
In a report Tuesday, the Nguoi Lao Dong newspaper quoted Anh as speculating that when she was away, her grandchild might have tried to change Nam's pants after he urinated, and accidentally made him fall, hitting his head on the floor.
Police said Anh wasn't licensed to run the nursery.
Since June, she had taken in three children, the newspaper quoted police as saying.
Investigation into the case is still underway.
