A NAZI war criminal exposed by The Sun while living freely in Germany was finally facing justice last night.

Prosecutors asked a court to jail evil Klaas Faber — the third most wanted Nazi fugitive.

Dutch-born Faber was caged for life in Holland in 1947 for shooting at least 22 Jews and resistance fighters while an SS death squad executioner. He escaped in 1952 and fled over the border to Germany.

The Sun tracked down the monster in July 2010 and confronted him in the Bavarian city of Ingolstadt, where he lives with his wife Jacoba.

The Dutch demanded his extradition and issued an arrest warrant. Israel also joined in calls for him to be jailed. But local Bavarian officials refused to act, saying a law passed by Hitler to protect foreign SS volunteers gave Faber immunity.

After an 18-month campaign the Bavarians have had a change of heart — thought to be because previously unknown atrocities came to light.

A court will now decide whether to order Faber, 89, to serve out his Dutch life sentence in a German jail.

Delighted Nazi hunter Dr Efraim Zuroff said: "Protecting a Nazi killer was a travesty."
