Islamist protesters detained dozens of officers and central security conscripts inside the Fayoum governorate headquarters, a security source said on Friday.

The protesters stormed the headquarters earlier today and declared a sit-in inside the building until deposed president Mohamed Mursi and all Muslim Brotherhood leaders who were detained or put under house arrest are released.

The force in charge of securing the building was held inside the building, the source told Aswat Masriya.

This force includes one major general, one colonel and dozens of soldiers, the source added.

The protesters refused to release the detained security personnel, one soldier said.
