A masturbating man was caught on camera, rubbing himself against the seat of a bicycle.
The owner of the bicycle, Per Edstrom had set up a camera, as he had grown tired of finding the tyres punctured, the Local reported.
The film, published by the Kvallsposten daily, shows how a hooded man approaches the bicycle, punctures the tyres and then proceeds to pleasure himself.
The owner told a newspaper that he had to install a camera, as he was irritated over all the punctures that he had to fix.
The man, who appears in the footage, can be seen holding a picture in his hand and Edstrom has expressed concerns that it might be of his girlfriend.
Ostersund police are investigating if there is any link between the recent spate of masturbation bike attacks with similar incidents from 2007.
