Austrian authorities returned a Stradivari violin worth at least €2 million (US $2.7 million) to its owner Wednesday, more than a week after it was stolen from a safe in the musician's apartment. Interior Minister Guenther Platter, the country's top security official, personally handed over the precious piece to musician Christian Altenburger at a morning news conference. Police said the instrument, which police said could be worth up to €2.5 million (US$3.4 million), was recovered unscathed in Vienna on Tuesday. Several members of a Georgian gang have been arrested in connection with the robbery. Altenburger said he was "overjoyed," the Austria Press Agency reported.
