Kiel prosecutor Birgit Hess said the collector, whose name she would not release for privacy reasons, is being investigated for possibly violating German weapons laws but remains free while the probe is ongoing.
In the search Wednesday and Thursday investigators also seized a torpedo and multiple other military items in addition to the Panzer V "Panther" tank and the 88mm flak gun, Hess told The Associated Press. German military engineers were called in to haul the tank out of the underground garage of the house in Kitzeberg, near Kiel.
