OSLO — A wrought-iron gate bearing a notorious Nazi slogan and believed to have been stolen from the Dachau concentration camp in southern Germany has been found in a suburb of Bergen, Norway, police officials in the two countries said on Friday.

The gate, a replica of the original bearing the phrase “Arbeit Macht Frei,” or “Work Sets You Free,” is one of the most photographed symbols of the camp. It was stolen in November 2014 in what the German authorities believed was an organized crime. An anonymous tipster alerted the Norwegian police to the presence of the gate.

Margrethe Myrmehl Gudbrandsen, a police spokeswoman in Norway, said the tip had come in this week, but she declined to give further information. She did not provide any details about the exact location of the discovery.

The Bavarian police, who investigated the theft, said they were working with their Norwegian counterparts to determine whether the gate that was found was, indeed, the one from Dachau. The Norwegian authorities had left the announcement of the discovery to the Germans out of deference for its symbolism, Ms. Gudbrandsen said.
