LONDON (AFP) - Islamist preacher Abu Hamza should not be extradited from Britain to the United States because he needs a brain scan to establish if he has a “degenerative” condition, his lawyer said Wednesday. The Egyptian-born cleric and four other terror suspects are expected to learn on Friday if their last-ditch bids to secure injunctions to prevent their removal to the US have been successful. A lawyer for Abu Hamza told the London High Court on the second day of hearings that the 54-yr-old was making an application “pending the obtaining of an MRI brain scan which has been recommended by two doctors”.
