Weekend commuters in New York were treated to an X-rated street performance on Sunday when two people decided to have sex on a Manhattan subway platform, police say. The incident happened at about 9:30 a.m. in the Bowling Green station, located in Lower Manhattan. According to a police report, the sexually charged couple went at it in full view of dozens of subway passengers. Police managed to get a photo of the man from a surveillance camera, but didn't get a picture of the woman, investigators say. They're now looking for help in identifying the frisky duo.
