London - Police who have been investigating claims that servicemen were poisoned during military research are to pass files to the Crown Prosecution Service. The two-year investigation centred on ex-servicemen's claims that they were exposed to nerve gas and other toxins after volunteering for research to find a cure for the common cold.
More than 20,000 servicemen have allegedly been exposed to chemicals including mustard gas, nerve agents, CS gas and LSD at the experiment centre in Porton Down, Wiltshire, most of them in the 1950s and 1960s.
