The Tokyo Metropolitan Police Department and the prefectural police departments of Saitama, Chiba and Kanagawa detained 77 men during a crackdown on lewd acts on trains and at stations from April 15-21.
According to the police, 78 incidents of groping and other lewd acts were reported. Of the 77 suspects detained, 49 were actually arrested. Of the 77, 37.7% (29) have a criminal record for molestation or performing lewd acts, police said. Also, over half (48) were company employees.
The targeted areas were the Keio, JR Chuo and Saikyo lines. Most incidents occurred in the train, followed by escalators in stations. The main offense on trains was groping, followed by taking up-skirt photos and indecent exposure.
Of those detained, 26 were in their 30s, 21 were in their 40s, 16 in their 20s, 9 in their 50s, and 5 were in their teens.
Police said there were no assaults in trains on the Saikyo line which has security cameras installed. A police spokesman said, "There are stickers that say cameras are installed, so perhaps that acted as a deterrent."© News reports
