Sherif Hassan is an Egyptian citizen and a Christian. Back in the summer he married Emma, a British citizen. Earlier this month they travelled to Egypt to join his family after the death of his father and to introduce Emma to the rest of his extended family. On arrival at Cairo airport, Emma was immediately deported, while Sherif was arrested on no charge. The reason for his arrest and detention appears to be connected with his peaceful exercise of his Christian faith.
