A man who tipped off German investigators about the location of a stolen Stradivari violin has had his claim for a payment from police thrown out by a court in Hanover. The insurers of the 1721 'Sinsheimer', which was stolen from a manor house near Hanover in October 2008 and recovered nearly a year later, have already paid the man €160,000. But he wanted an additional €150,000 from the police for helping them arrange a bogus transaction that led to the thieves' arrest and the safe recovery of the violin.
