"The stomach of the monstrous fish contained fragments of human bones, as well as German military artifacts dating back to the Second World War.
Alfons Brzozowski and Marek Zdanowicz were fishing near the Oder’s confluence with the Bóbr river on April 6, when they made an astonishing catch: a gigantic Wels catfish, measuring 12 feet (3.68 meters) and weighing 413 pounds (187.5 kg).
Their celebration was rapidly transformed into interrogation, and then disgust, when they opened the animal’s belly. Among a large quantity of half-digested fish, they discovered an old metal insignia dating back to Nazi Germany, as well dozens of human bone fragments.
The two fishermen rapidly contacted the police, who opened an investigation to determine the origin of the remains."
Sorry wont quite fit here but I had to copy it. Second biggest wells I have hear of. Also some sort of proof catfish can swallow people.
