Locals in Slovakia were this week horrified to find a river running through their small town flowing bright red with blood.
Roman Podbrezova, 65, from the foothill town of Myjava in Slovakia, had gone for a morning walk when he saw the river, which runs through the centre of the town, bubbling with blood.
According to CEN, he said: "I just could not believe my eyes. The river was dark red. It was like something from a horror film. Blood cascading through the centre of town."
Another local said: "This is really creepy. Yesterday evening I walked past here and it was its normal beautiful blue-green.
"Now it looks like someone slaughtered 1,000 virgins or something. I'm not superstitious, and we've never had any serial killers or anything like that here, but this isn't normal.
"How could a river fill with blood without some seriously evil event behind it?" he said. "I immediately called the police."
Police spokesman Elena Antalova said: "We are checking the source of the blood and what caused it.
"At the moment we are thinking it could have come from dead fish or maybe someone washed a barrel containing blood in the river.
Another possible answer to the mystery may be a slaughterhouse several miles upstream on the River Myjava. Usually its water is pumped into a retaining pool where it is filtered before being released into the river.
Police think the filtration system my have gone awry.
