"I was banned from travel at the Cairo International Airport now as I was heading to Beirut to participate in a conference on legal work," Amin wrote on his official Twitter account.
Airport security said in a statement on Thursday that the decision to ban Amin from travel came because in light shed of his alleged involvement in an illegal foreign funding case.
