Prague - Czech police reported Friday detaining David Duke, former leader of US extremist group the Ku Klux Klan, on suspicion of denying the Holocaust in a book.
Duke arrived in Prague earlier this week at the invitation of local neo-Nazis to publicize the Czech translation of of 1998 memoir My Awakening.
Police have charged him with denying in the book that the systematic mass murder of Jews and other ethnic groups by Nazi Germany during World War II ever took place, a hate crime in the Czech Republic punishable by up to three years in prison, police spokesman Jan Mikulovsky told the German Press Agency dpa.
