Islamabad, April 28: Shakil Afridi, a doctor who helped the US’ Central Intelligence Agency (CIA) track down Osama bin Laden, has been moved out of a prison in Peshawar to an undisclosed ‘safe location’ in another city, the media reported. Afridi had been imprisoned in the Central Prison Peshawar for almost seven years after he ran a phoney vaccination campaign in Abbottabad city to help the CIA track down and kill the former Al Qaeda chief in a controversial raid on May 2, 2011. A year later, Afridi was sentenced to 33 years in prison for involvement in anti-state activities by a tribal court.
