An American and two Britons have been sentenced for participating in a Mafia conspiracy to flood Britain with cocaine.

John O'Boyle, 49, a heavy equipment dealer from Detroit, was sentenced Friday to an 18-year prison term and David Raftrey, 38, and Lloyd Hibbert, 46, both of London, received 10-year sentences.Judge Kenneth Richardson referred to the "chilling link" between organized crime in Detroit and in Britain and said the three men had smuggled in 121 pounds of cocaine with a black market value of about $30 million. The "first of many consignments" was hidden in bulldozers, he said.
