Minya police on Wednesday arrested a leader from Jama'a al-Islamiya.
The suspect was reportedly carrying a shotgun and an Al-Qaeda flag.
He is charged with involvement in violence that followed the dispersal of the sit-ins staged in Rabaa al-Adaweya and Giza's al-Nahda Square in support of ousted President Mohamed Morsy.
The suspect owns a gym and lives in Ezbet al-Khashaba in Minya.
According to investigations, the 26-year-old suspect was implicated in attacks on government buildings and houses of worship in Minya on 14 August. He is also a member of Jama'a al-Islamiya.
