A couple in eastern Japan were arrested for allegedly neglecting their 3-month-old daughter and not seeking medical attention, causing her death, police said Wednesday.

Yuki Kanai, 29-year-old, and his 28-year-old wife Azusa, are suspected of not properly caring for their fourth daughter, Kia, who became malnourished and underweight due to an injury that left her unable to drink milk in August last year, the police said.

The parents from the town of Misato, Saitama Prefecture, north of Tokyo, did not take the daughter to the hospital, which could have prevented her death in September, according to the prefectural police.
