Egyptian security sources said that the leader of the Muslim Brotherhood, Dr. Essam Al-Erian, died of a heart attack in the notorious Scorpion prison in Cairo, aged 66 years.

The lawyer of the Muslim Brotherhood, Abdel Moneim Abdel Maksoud, said in statements to local newspapers that he received a call this morning from the Prisons Authority Department at the Ministry of Interior, informing him of the death of the Brotherhood leader Essam Al-Erian in his prison.

According to Abdel-Maqsoud, he and the Al-Erian family have not been able to see him for about six months, after the authorities suspended visits to prisons as a precaution to combat the Corona virus.

Al-Erian held several leadership positions in the group before he was arrested after the military coup.

Al-Arian was sentenced to several life sentences (25 years) in the years following the coup against the late President Mohamed Morsi, including the case of storming the eastern borders, the Qalioub events and the case of the Great Sea events.
