Police detain American at Pakistani airport Police detain American at Pakistani airport - Pakistan Pakistan cops hold American found with bullets in luggage at Peshawar airport Official says the man told them he was a diplomat Pakistani security forces on Tuesday detained an American citizen at an airport in the northwest of the country after bullets and a pistol magazine were found in his luggage, police said. Officer Dost Mohammad Khan said the man claimed to be an American diplomat as he was being detained at Peshawar airport. Pakistani security agencies identified him as John Arthur, NBC News reported. Tahir Ayub, a senior police superintendent, said that the American was supposed to fly from Peshawar to Islamabad on a Pakistan International Airline flight. "He has been detained at the airport and is under interrogation," the police official said. "We are in contact with the foreign office in Islamabad to check about his background and tell us if he has diplomatic immunity," he added. Embassy checking report A U.S. Embassy official said the mission "was looking into the report." The official didn't give his name because he was not authorized by Washington to be named in the media. The U.S. has a large consulate in Peshawar. The presence of American diplomats inside Pakistan emerged as a sensitive issue after a CIA contractor killed two Pakistani men in the eastern city of Lahore a year ago. U.S. officials insisted the shooter had diplomatic immunity, but Pakistan held him in jail for around two months, causing severe strain in U.S-Pakistan ties. The unilateral American-raid that killed Osama bin Laden in an army town in May last year also led to a fresh wave of suspicion against Western diplomats by the Pakistani security establishment, which was apparently stung by the realization that the CIA agents were operating in the country without its knowledge.
