On 11 September 2012, a large protest took place at the US Embassy in Cairo against "Innocence of Muslims", which had been created by an Egyptian Coptic Christian living in the US. On 12 September, Alber Saber's home was surrounded by a crowd calling for his death for heresy and atheism. The crowd attempted to break down the door, and also threatened to burn down the house. Saber's mother called the police for protection, and Saber was arrested by them the following day. Saber later stated that a police officer incited other prisoners to attack him in detention; he was beaten and cut on the neck with a razor. According to Amnesty International, Saber's home, where his mother and sister also live, continues to be the scene of angry protests.
