A man held on suspicion of assaulting his 10-year-old daughter just before she died late January, was served a fresh arrest warrant Thursday for allegedly slamming her against the floor about a month earlier, police said.

Yuichiro Kurihara, 41, was initially arrested on Jan. 25, the day after his daughter Mia, a fourth-grader, was found dead in the bathroom of their home near Tokyo. He is suspected of having doused her with cold water as part of the alleged assault.

An autopsy was unable to determine the cause of death, but found several bruises and internal bleeding, according to police.

Kurihara is newly suspected of thumping Mia's face against the bathroom floor and pressing her down at their home in Noda, Chiba Prefecture, probably between Dec. 30 and Jan. 3, police said. The daughter is believed to have sustained broken bones in the assault.

The police did not reveal whether Kurihara admitted the charge. He told investigators after the initial arrest he did not believe his action was wrong, because it was meant to "discipline" her.

Investigators said they have analyzed video footage and photo images that showed Mia with bruises, crying, and forced to stand for long periods.

Mia's mother, Nagisa Kurihara, 32, who was arrested earlier this month for allegedly failing to stop her husband from assaulting the daughter, has told investigators she knew of Kurihara's violence.

Police plan to investigate to what extent she was involved in the latest alleged assault.
