In HK a couple of years ago, a chio babe stepped onto a crowded
MTR train, and a guy went behind her n
started rubbing his tool on her behind, she turned around and
arrested him. She was an offduty cop, then later when they strip
searched him, they found he was not wearing any underwear,
apparently for better sensation, and had semen stains on his pants.
True! It was printed in the newspaper.
