German tank thieves re-arrested Published: April 26, 2008 at 6:02 PM Font size: SOFIA, Bulgaria, April 26 (UPI) -- Bulgarian authorities say two German nationals who allegedly stole a World War II tank have been re-arrested. Thomas Gmainer and Matheus Mayer had jumped bail last fall after they had been arrested by Bulgarian police while trying to dig up a German army tank that had been buried and used as a fixed gun position during the war. The Sofia News Agency reported Saturday the pair had already swiped one other buried tank, presumably in order to sell it to a private collector. The Defense Ministry said the government had requested the extradition of Gmainer and Mayer; however the decision would be up to a German court.
