TOKYO - A man who stabbed his ex-girlfriend to death in Japan learned her new married name and where she lived from the police officers who arrested him for stalking her, media reported Friday.
Hideto Kozutsumi was held in Kanagawa prefecture, southwest of Tokyo, last year on charges of stalking and harassing Rie Miyoshi after he repeatedly threatened to kill her in a series of emails following the pair's split.
Kozutsumi could only email because Miyoshi had married another man, taking his name, and moved to a different city.
Police arrested Kozutsumi for the harassment - reading out an arrest warrant that included his former lover's new name and location.
He received a non-custodial sentence and began pursuing her again by email, but without making threats, reports said.
Miyoshi asked the police to re-arrest Kozutsumi, but officers said there was nothing they could do because harassment by email is not a crime in Japan.
Repeatedly sending faxes or harassing by constant telephone calls, however, is an offence, police noted.
Some time later, Kozutsumi sought out Miyoshi and stabbed her to death before hanging himself, reports said.
Broadcaster TBS quoted a police official saying that reading out the arrest warrant was the appropriate procedure but that "in retrospect, measures could have been taken not to disclose her details".
