Museum officials at the former Auschwitz concentration camp in Poland have restored the metal entrance sign damaged in a theft 17 months ago.

The "Arbeit macht frei" (work sets you free) sign was stolen by a gang of Polish thieves acting at the behest of a Swedish far-right-winger.

Technicians unveiled the restored sign in the laboratory of the camp museum.

More than one million people, mostly Jews from across Europe, were murdered by the Nazis at the camp.

Most of the work to restore the damaged sign was done on site, but a master blacksmith welded it back together.

The museum's director, Piotr Cywinski, said the sign would probably form part of a new exhibition.

A copy of the original has been placed above the entrance gate....
