Japanese police have arrested a man for allegedly drugging and sexually assaulting more than 100 women who believed they were taking part in a medical study.
Adverts were released seeking volunteers for “clinical research measuring blood pressure during sleep” over the two years to November 2013, and scores of women responded.
Detectives believe that the 54-year-old fake researcher, Hideyuki Noguchi, 54, gave the women sedatives after luring them to hotels and hot spring resorts. Once the women were unconscious, he raped them and filmed each assault, police said.
Footage of the attacks was posted on the internet or sold to producers of porn films, allegedly netting Noguchi more than ¥10m (N16,700,000), TBS and other broadcasters said. Noguchi is not known to have any medical training or expertise.
Police in Chiba, east of Tokyo, said officers had confirmed at least 39 victims, aged from their teens to their 40s, in Tokyo, Chiba, Osaka, Tochigi and Shizuoka, but the number he attacked is thought to be more than 100.
