On yer bike! Swedish police are on the lookout for a hooded man, after a rather unusual video of him a masturbating on a bike was caught on CCTV.

The man who is seen rubbing himself against the seat of a bicycle was caught in the act after the bike’s owner Per Edstrom set up a CCTV camera outside his house to find out who exactly had been slashing its tyres.

In the video, the man also seems to be looking at a picture in his hand and Edström expressed a concern that it might be a picture of his girlfriend.

"My girlfriend finds it all a little concerning, you never know if he has checked her out in some way, and whether it is a picture of her he has in his hand when he is masturbating," he told Swedish newspaper Kvällsposten.

Bizarrely, this isn’t the first time that an incident like this has happened and police are suggesting that there might be a link between the two cases.

In 2007, a 35 year old man was arrested for masturbating on 20 bicycles in Stockholm.

Speaking about this incident Edstrom said that he was "not scared of him” but “just irritated over all the punctures I have had to fix.”
