Police said Thursday that a man in Shirakawa, Fukushima Prefecture, has been arrested for adding battery acid to a bottle of eye drops, causing serious injury to his girlfriend's son.
Tamotsu Ito, a 48-year-old truck driver, is accused of putting battery acid in the eye drops between April and December of last year, NTV reported. According to police, Ito -- who is married -- encouraged the woman he was dating to use the drops. The woman is believed to have regularly used the drops on her son, who was 4 at the time, resulting in serious injury. The boy had been prescribed the eye drops for an eye inflammation.
The damage to the boy's eyes was initially identified by a doctor during a medical examination in December. The police were informed of the incident by the hospital, according to NTV.
Doctors say there is a possibility the boy will lose the sight of his right eye.
The boy is currently in the protective custody of a Fukushima child counseling center. His mother told police she did not know the eye drops had been tampered with, NTV reported.
Police say Ito has confessed to adding the acid to the eye drops. He was quoted by police as saying he hated the boy.© Japan Today
