Tokyo police arrested a 49-year-old woman on Tuesday after she reportedly admitted abandoning the body of her stillborn baby in a coin locker and leaving it there for several years.

On Monday police officers found the decaying body of an infant wrapped in a plastic bag in a baggage locker near Uguisudani Station in Taito Ward, Tokyo, they said. After turning herself in, the woman was arrested on suspicion of abandoning a body.

Police became aware of the situation when Emiri Suzaki went to a police station in neighboring Arakawa Ward on Monday morning and informed police she had abandoned the stillborn baby's body after giving birth to it four or five years ago. She admitted to keeping the remains in the locker, all the while paying the storage fees, they said.
