Police have arrested a man on suspicion of assault after his 10-year-old daughter died last week at their home in Chiba Prefecture.
Yuichiro Kurihara, 41, was arrested Friday on suspicion of assaulting his daughter Mia, whose body was found with several bruises on it.
The girl had reported to her school in November 2017 that she had been "bullied" by her father and was taken into protective custody for about seven weeks after a bruise was found on her cheek.
