Egyptian authorities in Beni Suef arrested the son of Muslim Brotherhood leader Mohamed al-Beltagy along with three others on Sunday, a security source told the state news agency MENA. 

Amar Mohamed al-Beltagy, Mohamed Hussein Abdel Azeem, Tarek Mostafa Abdel Aziz and Galal Younes were arrested at Abdel Azeem's Beni Suef residence earlier on Sunday.

The source added that the arrests came in response to orders made by the general prosecutor to summon and bring them forward, pointing out that all the necessary legal procedures are being taken with them.
