A woman trying to make "manure bombs" using stockings, slipped into a slurry tank and fled the scene naked, German police said on Friday.
Two women entered a farm in the northern village of Eberholzen on Wednesday evening and started to fill the stockings with manure.
"One of them slipped into the manure tank, right into the cow muck," said a spokesman for local police. "The other one helped her out. We found their clothes in a field. One seems to have run off completely naked, the other in her underwear."
Police said it was unclear what the women had intended to do with the "manure bombs," but added the incident could be linked to victory celebrations surrounding the Euro 2008 semi-finals on Wednesday evening, when Germany beat Turkey 3-2.
"The women can get their clothes back from the local police station — unwashed," the spokesman added.
