A young woman has in five instances gotten off the train by Mørdrup Station in north Zealand only to find that a man has masturbated onto her bicycle seat.

The saddle-polishing perpetrator has so far only struck on Wednesdays and only when the woman in question leaves her bicycle at Mørdrup Station.

“At first I thought that it was some kind of sick joke, but when it happened for the third time I decided it was enough and reported it to the police. It’s bloody disgusting,” the 19-year-old woman, who wishes to remain anonymous, told Ekstra Bladet tabloid.

The woman said she didn't have a clue who was behind the unwanted bicycle lubrication but feared that children could witness the man ‘adjusting his helmet’ from a nearby playground.

North Zealand’s assistant police commissioner, Henrik Hattel, confirmed that he had received several reports from the woman, most recently on Thursday. He said it was a conscious decision to go public with the case. 

“We’re hoping that this will get the freak to quit doing it. That’s the most important thing for us. It’s difficult to say how we should punish the man,” Hattel told Ekstra Bladet.

Although indecent exposure usually involves someone witnessing another person doing something sexual publicly, the police still believe that this case falls under the law concerning indecent exposure.

"Otherwise the woman wouldn’t have called us. Her decency has been violated on some kind of level,” Hattel said.

The police have not heard from anyone who has seen the man ‘applying his hand brake’ to the woman’s bicycle seat and they haven’t looked at the liquid to ascertain if indeed it was semen. They do not, however, question the validity of the woman’s report.
