The mother of a 10-year-old girl who died last month at their home in Chiba Prefecture has told police that she sometimes gave the girl no food, at her husband's insistence, in the days before her daughter's death, investigative sources said Tuesday.

Nagisa Kurihara, 31, was sent to prosecutors that day. She was arrested a day earlier for allegedly failing to stop the assault of her daughter Mia.

Mia was found dead on Jan. 24 inside the bathroom of their home, in the city of Noda, with multiple bruises on her body. Nagisa's husband Yuichiro, 41, was arrested the next day on suspicion of assault, but an autopsy has failed to determine the cause of Mia's death.
