ISLAMABAD (AFP) Pakistan may quickly release an American construction worker in poor health who is being held on suspicion of wanting to kill Osama bin Laden, a senior official said Friday. Gary Brooks Faulkner was arrested Monday in the remote mountains of Chitral, once a rumoured hiding place of bin Laden, near the Afghan border, armed with a pistol, dagger, long sword and night-vision equipment. Faulkner purportedly told police he was on a solo mission to hunt down bin Laden, the worlds most wanted man with a 25 million dollar bounty on his head, and he has become known in the United States as the American Ninja. Faulkner is still in Pakistans custody and is being interrogated, a senior official told AFP on condition of anonymity. The US national will be released if nothing substantive is found against him after the interrogation. Asked if he would be handed over to the US embassy, the official said: It should be done sooner than later because Faulkner is sick. US consular officials met Faulkner in Islamabad on Thursday. A Christian believer, he suffers from high blood pressure and kidney problems, which relatives say requires dialysis. The official said Faulkners weapons had raised alarm bells, but that he had posed no problems on previous visits to Pakistan, another indication that authorities may be thinking about an imminent release.
