Agence France Press reports (thanks to Prof. Howard Friedman at Religion Clause for the pointer):
Cairo police arrested a man who allegedly … posted [statements on Facebook] ‘that were insulting to the Koran and the Prophet Mohammed and Islam and Muslims.’ …
The youth was referred to the prosecution, which may charge him under a law that penalises ‘insulting religion.’
I couldn’t find more details on the story; please let me know if you know more.
