Evil Klaas Faber, 88, looked like an ordinary OAP when The Sun went to confront him about his war crimes.
But his white hair and glasses hide a shocking past as a bloodthirsty killer who volunteered for Adolf Hitler's notorious SS and a roving Gestapo death squad.
Faber was sentenced to death after being convicted of war crimes in 1947. But his sentence was commuted to life imprisonment, and in 1952 he escaped from prison in Breda, Holland, and fled to sanctuary in Germany.
Demands by Britain and other nations to hand over Faber - listed as the fifth most-wanted Nazi fugitive - have since been rejected by Germany.
Incredibly, officials still protect the Dutch-born killer and insist he is immune from extradition after Hitler granted him German citizenship as an SS volunteer.
Local privacy laws mean that Germans cannot be told Faber is a war criminal, or see photos of him enjoying his freedom.
But The Sun found Faber in the medieval town of Ingolstadt, where he lives with frail wife Jacoba. The name K. Faber marks the doorbell on his modern flat.
After years as an anonymous office worker at Audi, Faber now enjoys a cosy retirement relaxing in local parks and going on shopping trips in his VW Golf.
Neighbours say the dad of three is quiet, but friendly and polite.
The Sun confronted him and asked if he felt any remorse for his crimes or compassion for his victims and their relatives.
Faber's smile immediately vanished, replaced by an icy stare and grim silence.
His trial heard he was an enthusiastic Nazi who volunteered to join the SS in 1940, then travelled around northern Holland ruthlessly slaughtering Jews and Dutch resistance fighters.
He rose to become an officer with the notorious SD secret police and worked for the Gestapo as an executioner at Westerbork concentration camp, where teenage diarist Anne Frank was held.
He was convicted of murdering at least 22 victims, but the court heard he personally carried out mass shootings and experts believe the real toll was much higher.
Faber was then one of seven Nazi officers who escaped from Breda prison on Boxing Day 1952.
They fled to Germany, where they were welcomed at the border and given coffee and cakes by sympathetic customs officials.
The gang were given token fines for illegally crossing the border, then set free. German authorities still honour the special privileges granted by Hitler himself to his most hardcore followers.
Faber became a German in 1943 under the "Fuhrer's Law" - a personal decree granting German citizenship to foreign Nazi volunteers.
It is the only one of Hitler's laws never to have been revoked, and Germany still uses it to deny repeated attempts to return Faber to prison in the Netherlands.
Outraged Holocaust campaigners last night urged Germany to stop protecting Faber and hand him over to serve his sentence.
Simon Wiesenthal Centre director Dr Efraim Zuroff said: "He is one of the most evil men alive. For Germany to continue shielding him is a shocking stain on the nation's reputation.
"We are talking about someone who volunteered for the SS so he could help Hitler's regime turn his vile beliefs into reality. He didn't just support the Holocaust, he actively helped those behind it.
"The families of those he killed deserve justice, and it's time for Germany to stop hiding behind a law that Hitler brought in."
Sickened Arnold Karstens, of the charity War Crimes Investigations, said: "It is beyond belief that this man is free. Germany should hang its head in shame.
"Faber's crimes are so extreme he should die in prison. What makes it even worse is he has never shown remorse. It is sickening to see him enjoying freedom."
German authorities last night confirmed that Faber was immune from prosecution and extradition, despite repeated requests by the Netherlands to hand him over. State prosecutors decided in 2006 to classify Faber's crimes as manslaughter. So a time limit on trying him in Germany - which does not apply to murder - has now expired. A spokesman added: "Klaas Faber is a German citizen and cannot be extradited for this."
