A 72-year-old man has been arrested on suspicion of negligent injury after one of his four Dalmatians escaped from his home in Onjuku, Chiba Prefecture, and bit a woman in her 80s walking on the street, police said.
The suspect, Masato Hamana, is accused of failing to manage the dogs properly at his home in July. The dog that attacked the woman is about 60 centimeters long, according to police.
The woman was bitten on both legs and suffered a serious injury to her right calf.
Earlier warnings went unheeded
The same dog had injured people near the home before. Police and the public health center had instructed Hamana on how to keep the animals, including telling him to stop walking two dogs at once, and had issued warnings.
He did not comply, and the dogs injured someone again. That led to his arrest.
Hamana has admitted to the allegations, police said.
