A man indicted for sex offenses against five women has now been accused of abusing his authority to access personal information on at least three of the alleged victims from computers at the ward office where he worked.

Kenichiro Takahashi, 29, was re-arrested over his suspected violation of a ward ordinance on the protection of personal information and also for trespassing on the property of one or more victims, officers of the Metropolitan Police Department in Tokyo said Jan. 11.

Takahashi, a local resident, is choosing not to answer investigators' questions, they said.

The former temporary Nakano Ward government employee was arrested earlier and indicted on charges of trespassing homes, forcible indecency and attempted forcible indecency. Police say Takahashi obtained information on at least three of these victims through the ward office’s computerized registration system.

Investigators also found personal data on dozens of women in their 20s and 30s stored in his personal computer and cellphone.

Takahashi was first arrested in July 2016 over an incident the previous March in which he allegedly sneaked into the apartment of a woman in her 20s late at night in the ward and hugged her. The two were not acquainted and Takahashi fled after the victim put up a fight, police say.

He is also suspected of entering the apartment balcony of another Nakano Ward resident in her 20s from 2014 to 2016, as well as illegally obtaining her personal information through Nakano Ward’s computer system during the course of his work, according to police investigators.

Nakano Ward said the suspect was employed intermittently as a temporary worker from 2014 to 2016. At the time, he had been given the authority to freely access personal information handled by the ward government.

He was in charge of inspecting address signs in streets and sending out notices regarding the My Number national identification number program, according to the ward office.

Having been assigned his own ID name and password, Takahashi could search and access the ward’s “resident information foundation system” to acquire private information about residents, such as names, gender and number of people in each household.

Access history to the databank was recorded on the server, but the ward office did not bother to check whether the system was abused.

There have been a number of instances of local government employees overstepping the boundaries on personal data.

In 2016, a city employee of Iwata, Shizuoka Prefecture, was punished for obtaining a woman’s address via a city hall computer while a Gifu prefectural office employee was arrested on suspicion of stealing the personal data of about 10,000 people.
