How did gate stolen from Dachau concentration camp end up in Norway?

Police investigating how an iron gate stolen from a Nazi concentration camp in Germany ended up in Norway say they have no evidence to work on.

The gate with the slogan 'Arbeit macht frei' - work sets you free - on it disappeared in 2014 from the Dachau concentration camp in southern Germany.

Yad Vashem was found on 28 November under a tarpaulin at a parking lot in Ytre Arna, a settlement north of Norway's second largest city, Bergen.

Police spokeswoman Kari Bjoerkhaug Trones said: "It has been there for quite some time with some junk under a tarpaulin.

"Our forensic teams have found no useable evidence like DNA."

The Nazis established the concentration camp near Munich in 1933.

The missing gate, which measures 190cm by 95cm, was originally set into a larger gate at the entrance of the camp.

More than 200,000 people from across Europe were held at Dachau and more than 40,000 prisoners died there.

The camp was turned into a memorial site and the gate's theft in November 2014 was viewed as a desecration.

The Dachau memorial's director described the gate as "the central symbol for the prisoners' ordeal".

Israel's Yad Vashem memorial blasted the theft as "an offensive attack on the memory of the Holocaust".

Jean-Michel Thomas, president of the International Dachau Committee that represents former prisoners, survivors and victims from Dachau, was "very happy" with the recovery of the gate.

A replica was installed in the missing gate's place last year - one of a number of events to mark the 70th anniversary of the liberation of the camp by US forces in April 1945.
