A man has been jailed for four-and-a-half years for the theft of a Stradivari violin in London. The instrument, valued at £1.2m, was stolen from South Korean violinist Min-Jin Kym while she was eating at a branch of Pret A Manger at Euston Station in November 2010. John Michael Vaughan, 30, and two boys aged 15 and 16, admitted the theft at Blackfriars Crown Court in March. The 16-year-old was given ten months' detention; the 15-year-old is yet to be sentenced. The Stradivari violin, along with a £62,000 Peccatte bow and another bow worth £5,000, has not yet been recovered.
