Tokyo, Feb 5 (IANS): Japanese police claimed that around 100 women who thought they were participating in a sleep study were actually drugged and raped and their recorded acts were sold to porn sites.
Authorities arrested 54-year-old Hideyuki Noguchi after one of the women saw herself in a video, CNN reported.
Police investigated and arrested Noguchi, who now faces charges of incapacitated rape in dozens of cases.
Authorities say Noguchi has told them the number of victims is about 100.
The assaults allegedly began in 2012 when, according to police, Noguchi took out advertisements seeking participants for a sleep study.
But authorities say Noguchi has no medical training and the study was merely a ruse to isolate women, drug them, assault them and film their acts.
Police say Noguchi sold the videos to porn sites, making around $100,000.
