"Alleged Japanese stalker studied reflection from photos of pop star's pupils to find out where she lived"

Text from The Japan Times, 10/12/19.

A man arrested on suspicion of stalking a female pop idol used the reflections of her pupils in photos she shared on social media and Google Street View to find where she lived.

Tokyo police declined comment on the specifics of the investigation but confirmed Friday that 26-year-old Hibiki Sato was arrested Sept. 17 on suspicion of indecent behavior in connection with stalking and causing injuries to the 20-year-old woman.

The police official, who spoke on condition of anonymity, said the case was related to the reports about a stalker and pupil images.

Police described Sato as an “avid fan.”

NHK and other media reported this week that details in the woman’s selfies were used to identify the train station she frequented. They said Sato looked at other images she shared, such as her apartment, to figure out where she lived.

Police say he hurt her and committed indecent acts, such as groping her after accosting her from behind and knocking her down.

Tokyo Shimbun, a metropolitan daily which reported on the stalking case, warned readers that even casual selfies may show surrounding buildings that will allow people to identify the location of the photos.

It also said people shouldn’t make the V-sign with their hand because fingerprints could be stolen.

Cyberstalking has been a problem for years, with criminals and perpetrators of domestic violence using hacking, clandestine activation of microphones and cameras and other methods to track their victims.

It’s unclear how prevalent the use of high-resolution photos to locate potential victims might be.
