Hungarian authorities have detained, grilled and put under house arrest a 97-year-old Laszlo Csatary, who is accused by the Wiesenthal Centre of organising the deportation to their deaths of some 16,000 Jews from the ghetto of Kosice in present-day Slovakia in World War II. He tops the Simon Wiesenthal Centre's dwindling wanted list of surviving suspected Nazi war criminals. "Our viewpoint is that at this age, being under house arrest is already quite a shock," state prosecutor Tibor Ibolya said on Wednesday. "We have to make sure that this man remains alive and is able to stand trial." While there between 1941 and 1944, Csatary beat, brutalised and sent 16,000 Jews to their deaths in Ukraine and to the gas chambers at the Auschwitz extermination camp.
