Intelligence agencies re-arrested an American detained in the country's volatile border region and were questioning the man, police said on Wednesday. Juddi Kenan, 20, was carrying a laptop computer when arrested on Monday at a checkpoint in Mohmand district. District Police Officer Waqif Khan said Juddi was released from custody on Tuesday but was picked up hours later at his home in Peshawar. "Intelligence agencies are required to quiz him again for further satisfaction," he said. In Washington, US State Department spokesman Sean McCormack said US officials had visited and spoken with the man and were doing everything they could for him. He declined to provide more specific details including confirming the name because of privacy concerns.
