A Pakistani commission has imposed a travel ban on a Pakistani doctor who assisted the United States in the raid that killed al-Qaida chief Osama bin Laden.

Dr. Shakeel Afridi ran a fake polio vaccination drive in Abbottabad in an effort to obtain DNA samples of bin Laden's family.

He is currently being detained by Pakistani authorities, but has not been charged with a crime.

The government-appointed Abbottabad Commission, which is investigating the raid, said in a statement Tuesday that all persons involved in the incident would be banned from travelling abroad without special clearance.
