German authorities have arrested a 93-year-old man accused of having been a guard at the Nazi death camp at Auschwitz.
Prosecutors say Hans Lipschis worked at the camp for four years and was complicit in murder.
Mr Lipschis acknowledges he served with the Waffen SS at the camp in occupied Poland, but claims he was only a cook, the BBC reports.
Last month, the Simon Wiesenthal Center named him as number four on its list of most-wanted Nazis.
The organisation accused him of participating in the mass murder and persecution of innocent civilians, primarily Jews, at Auschwitz between October 1941 and 1945.
