In a case in which a former instructor of Yotsuya Otsuka, a major junior high school entrance exam cram school, was arrested and charged with voyeurism of a female student of his students, the Metropolitan Police Department arrested the former instructor by November 7 on suspicion of voyeurism of another seven students. This concludes the investigation into the series of incidents involving the former lecturer.

The defendant, Takasho Mori (24), who worked as an instructor at Yotsuya Otsuka, a major junior high school entrance exam cram school, was indicted last month on charges including violating the Tokyo Metropolitan Government's nuisance prevention ordinance for taking voyeuristic photos of the underwear of two female students, and was also extradited on suspicion of voyeurism of three other female students.

In the subsequent investigation, it was found that he was suspected of taking voyeuristic photos of seven other female students from May to August, and the Metropolitan Police Department extradited the former teacher to the police station on suspicion of violating the Tokyo Metropolitan Government's Nuisance Prevention Ordinance by November 2.

A total of 3 children have been victims of voyeurism.

The former instructor was also arrested on suspicion of writing down the names and addresses of children in the cram school database in inappropriate places and possessing obscene images of children collected on the Internet, which ended the investigation of the series of cases.
