(CNN) -- An elderly man suspected of Nazi war crimes has been arrested in Hungary, prosecutors said Wednesday, after a worldwide Jewish rights organization discovered him living in Budapest.
Ladislaus Csizsik-Csatary is accused of sending more than 15,000 Jews to the Auschwitz concentration camp in the spring of 1944, the Simon Wiesenthal Center said.
The center considers him its most wanted Nazi war criminal.
The Simon Wiesenthal Center found Csizsik-Csatary as part of its "Last Chance" project, said Efraim Zuroff, director of the center's Israel office.
Csizsik-Csatary served as a senior Hungarian police officer in the city of Kosice, which is now in Slovakia but was under Hungarian rule in the 1940s, the center said.
"He was a commander of a ghetto," Zuroff told CNN.
