There is a very detailed account published in Rogaland Avis about a decade's worth of shitting on a Norwegian golf course.

Beginning in 2005, groundskeeper Kenneth Tennfjord claims a mystery person has been relieving themselves in the holes at the Stavanger Golf Club course with little to no remorse, and this person hasn't stopped since.

UPI also has a writeup about the Turd Bandit and provides some important answers to burning questions:

Do we know the person's gender? Not 100 percent, but the assumption is it is a man "because the poos are too massive to be from a woman."

Does he have a favorite hole in which to shit? "He has a couple of favorite holes."

Does he have a regular schedule? "He poos only on weekdays. On weekends I have never found poo on the golf course."

Has the club done anything to counteract this pooping menace? Yes, "the club installed high-powered spotlights to discourage the defecation, but the poop-etrator disabled them."

Did it work? No. "He climbed up a tree next to the lights and wriggled far out on a branch and dismantled the spotlights. How he managed the feat without electrocuting himself or falling is a riddle."

Does anyone have any theories, or possible motives? "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," said the course's managing director.
