The Benton Horde, a priceless collection of ancient Roman silver, 14. (disappeared) from its display cabinet in the British Museum. At today‘s emergency press conference, the Museum director John Clive said, that according to his theory, the treasures 15. (had probably been stolen) by a professional gang on behalf of a specific collector. The matter is that the stolen silver 16. (is) very well-known and it 17. (has never been sold) on the open market.
Ten museums 18. (have been robbed) in the last six months and the number 19. (has been rising) steadily over the last few years. The Benton Horde 20. (is considered) one of Britain‘s most important collections of Roman silver. It 21. (had been lying) undiscovered for almost sixteen centuries beneath a Sussex field until it 22. (was found) incidentally in 1926.
