Japanese idol Ena Matsuoka was attacked outside her home last month after a fan figured out her address from selfies she posted on social media — just by zooming in on the reflection on her pupils, according to media reports.
The fan, Hibiki Sato, 26, managed to identify a bus stop and the surrounding scenery from the reflection on Matsuoka’s eyes and matched them to a street using Google Maps.
Sato had even approximated the storey Matsuoka lived on based on the windows and the angle of the sunlight in her eyes.
Matsuoka, 21, a member of the J-pop group Tenshitsukinukeniyomi (天使突抜ニ読ミ), was attacked outside her home in Tokyo on Sept 1 by Sato, who had been waiting at a bus stop.
She had just reached her door when Sato approached her from behind, covering her mouth with a piece of cloth.
He dragged her to a dark corner and molested her, injuring her face in the struggle.
Sato admitted to the attack after he was arrested on Sept 17 and revealed that he was a huge fan of Matsuoka.
Fans of J-pop groups have called for better protection of female idols after several high-profile stalking and assault cases in recent years.
Maho Yamaguchi, ex-member of pop group NGT48, spoke out in January about an alleged assault in which two men entered her home and tackled her.
Japan also revised its anti-stalking laws to cover online harassment after singer Mayu Tomita was stabbed dozens of times by a stalker.
Tomita had tried to report her stalker 12 days before the attack, but police dismissed the threat.
