Laszlo Csizsik-Csatary, 98, faced charges of torture and deportation of thousands of Jews to concentration camps while working as a police commander in a Hungarian ghetto.
Hungarian Csizsik-Csatary succumbed to pneumonia in Budapest on Saturday, his lawyer said today.
Csizsik-Csatary was found guilty of whipping Jews while overseeing a detention camp in the Nazi-occupied eastern Slovak city of Kosice, then a part of Hungary, in 1944, and was sentenced to life in absentia in 1948.
He was able to flee to Canada where he claimed to be a Yugoslav national and was granted citizenship.
Csizsik-Csatary was able to live an anonymous life in Canada, and worked as an art dealer before being stripped of his citizenship in the 90s when it emerged that he had lied on his application.
Following his dispatch from Canada he lived hidden in Hungary until he was detained last July.
In 2012, The Simon Wiesenthal Center named Csizsik-Csatary their most wanted war crimes suspect.
‘Csatary was responsible for sending 15,700 people to death camps,’ Simon Wisenthal centre’s director Efraim Zuroff, told the Sun last year.
‘He was known to be a sadist, he had a determination to round all Jews up and forcibly deport them to Poland.’
