Thieves Steal Rhino Heads From Irish Museum Animals were killed more than a century ago By Newser Editors and Wire Services Posted Apr 18, 2013 2:35 PM CDT 8 comments Comments African rhinoceroses are seen at Bao Son Paradise Park, a private zoo in Hanoi, Vietnam. (AP Photo/Na Son Nguyen) (Newser) – Masked men stole stuffed rhinoceros heads containing eight valuable horns from the warehouse of Ireland's National Museum, a heist being linked to an Irish Gypsy gang that specializes in such raids across Europe. Police said three men raided the storeroom in Swords, north of Dublin, on Wednesday night and tied up the lone security guard. A museum official said the four heads—three of black rhinos from Kenya, one of the virtually extinct white rhino from Sudan, all killed more than a century ago—were removed from display last year and put into storage specifically to safeguard them from thieves. They could fetch $650,000 on the black market. Three of the five species of rhinoceros in Africa and South Asia have been hunted to the verge of extinction because their horns command exceptionally high prices for use in traditional Asian medicine chiefly in China and Vietnam, where the powdered horn is marketed as an aphrodisiac and even as a cure for cancer. In 2011, Europol issued a warning that an Irish Gypsy criminal network based in the County Limerick village of Rathkeale was responsible for dozens of thefts of rhino horns across Europe.
