Police have arrested four men at a Cambridgeshire travellers' site wanted in connection with the theft of "priceless items" from museums and auction houses in England in 2012.
The four, aged 24, 41, 44 and 56, were arrested in a dawn raid after officers broke down the door of a mobile home at Smithy Fen travellers' site in Cottenham.
They were among 19 arrested by officers from 26 forces in an operation that also involved the Serious Organised Crime Agency (Soca).
