97-year-old Laszlo Csatary, who has been held under house arrest since 18th July following accusations by the Simon Wiesenthal Centre, was cleared on Tuesday by Hungarian prosecutors of a charge of organising the 1941 deportation of 300 Jews.
However a bigger charge related to the deportation of 15,700 people to Nazi death camps in 1944 remains under investigation.
The issue has been complicated by the fact that the alleged offences took place in the city of Kosice (Kassa), which was in Hungary at the time but is now in Slovakia. As a result, there have been calls in Slovakia for Csatary to be extradited and tried in Slovakia.
Csatary denies all charges. He was sentenced to death in absentia by a court in Czechoslovakia in 1948 but had already left the country and moved to Canada, eventually returning to Hungary in 1997.
