The man was first seen on Thursday night pleasuring himself at the Willy’s store entrance, the Nerikes Allehanda newspaper reports.
Described by witnesses as sporting a deep sun tan and masturbating shamelessly, the man was reported to police shortly after 8pm.
But by the time police arrived on the scene, the mystery masturbator had vanished on a bicycle.
While store personnel reportedly considered the incident inappropriate, they opted not to file a formal complaint.
On Friday, however, the 35-year-old came again to his favourite spot outside Willy’s to give himself a helping hand.
But this time police were primed and ready to strike as soon as the man began to busy his hands.
Police are now preparing to launch a preliminary investigation into bringing sexual molestation charges against the man, who will soon be interrogated by police as part of the process.
