Four recent graduates of a Turkish university have been arrested for displaying a cartoon mocking the nation¡¯s president at their graduation ceremony.

The students at Middle East Technical University in Ankara made and carried a long banner printed with a cartoon of animals whose faces resembled Recep Tayyip Erdo?an, entitled ¡°The World of Tayyip¡±, , citing a report from the state-run Anadolu agency.

Anadolu?reported that the four had been ¡°arrested¡­in the course of an investigation into a sign containing defamation of Erdo?an¡±.
