Egyptian security officials say the Muslim Brotherhood's supreme leader has been arrested in a coastal city and flown to Cairo on a military helicopter.
The officials said Mohammed Badie was arrested on Wednesday night in a resort village in Marsa Matrouh, a Mediterranean coastal city west of Cairo not far from the Libyan border. He had been staying in a villa owned by a businessman with Brotherhood links.
The officials spoke on Thursday on condition of anonymity because they were not authorized to speak to the press.
Ousted President Mohammed Morsi hails from the Brotherhood, of which he was a longtime leader.
Badie is on a wanted list of more than 200 Brotherhood officials and leaders of other Islamist groups.
