The report indicates that AFP is the source, but no link and I don’t see it on the AFP website. The short al-Ahram post states:
Egyptian security forces on Wednesday imposed a travel ban on President Mohamed Morsi and several top Islamist allies over their involvement in a prison escape in 2011, security officials said. Airport officials confirmed to AFP that they had received orders to prevent the leaders — including Morsi, Muslim Brotherhood chief Mohammed Badie and his deputy Khairat al-Shater — from travelling abroad.
