Footage of the bizarre bike bonk shows a hooded figure straddling the rear tire, while clutching a piece of paper.
The man then punctures a tire and masturbates while it deflates.
Police in the city of Osterlund are probing a possible link to a similar string of crimes that occurred in the area back in 2007.
Then a 35-year-old man was arrested for allegedly slashing the tires of twenty bikes, before ejaculating over the saddles.
Meanwhile, the bike’s owner Per Edstrom insists he doesn’t hold any grudges – he just wants the mystery man to leave his beloved bike alone.
He said: “I am not scared of him, just irritated over all the punctures I have had to fix.” (!?) -
