The Muslim Brotherhood has condemned the arrest of its leader Mohammad Badie over allegations of inciting violence and murder.
A Brotherhood spokesman said the arrest was part of a plot against the 2011 revolution that ousted Hosni Mubarak.
According to the BBC, Badie was detained near the site of a Cairo protest camp cleared by police last week.
At a news conference, Khaled Hanafi, a member of the Freedom and Justice Party - the political wing of the Muslim Brotherhood - said the organisation would not be thrown off course by Badie's arrest.
Badie has reportedly been temporarily replaced as 'general guide by Badie's second deputy, Mahmoud Ezzat.
Badie, 70, is facing charges of inciting violence and murder over the deaths of eight anti-Brotherhood protesters outside the movement's headquarters in Cairo in June, the report added.
