Someone has been defecating in golf holes on a course in Norway for the past decade.
The serial plopper has repeatedly soiled the course at Stavanger Golf Club and has a couple of "favourite holes" where the culprit likes to do their business.
Groundskeeper Kenneth Tennfjord is determined to find the mystery toilet troublemaker and is convinced he's looking for a man because of the size of the stools.
Tennfjord told Norwegian paper Rogaland Avis: "He has a couple of favourite holes. And we know it is a man because the poos are too massive to be from a woman!"
Club managing director Steinar Floisvik added: "Our idea is that it could be someone who, for unknown reasons, hates the game of golf. Alternatively, the person may have a fetish or suffer from mental problems."
