A Peruvian diplomat was charged with smuggling 44 pounds of cocaine, valued at $10.3 million, into Britain in a diplomatic pouch, a British official and Peruvian sources said. A Customs and Excise spokesman said Jose Manuel Pacheco Nunez, 30, who was not accredited to Britain, was arrested in a London hotel after arousing the suspicions of Customs officers at Heathrow airport. The spokesman said that because Pacheco is not accredited to Britain he does not enjoy diplomatic immunity. In Lima, Peruvian Foreign Minister Guillermo Larco Cox said Pacheco is a second-level diplomat who may be dismissed from the Foreign Service. Sources there said Pacheco was in charge of the ministry’s computer system.
