A 35-year-old woman has been arrested in Chiba Prefecture for allegedly forcing her 5-year-old daughter — who is allergic to dairy products — to drink milk, causing a severe allergic reaction.

Police arrested Chiharu Saku, a company worker who lives in the city of Nagareyama, on suspicion of attempted murder. Saku is alleged to have knowingly forced her daughter to drink milk despite her allergy. The reaction, called anaphylactic shock, involves breathing difficulties and can be life-threatening, according to the police.

Saku is suspected of forcing her daughter to drink the contents of a 125-milliliter milk carton on Sunday, police said. The daughter was hospitalized but is recovering, they said.
