Egypt's Muslim Brotherhood leader, General Guide Mohammed Badie, has been arrested in Cairo for inciting violence, state officials said.
Badie, who had been on the run since the interim government tried to suppress Morsi supporters, was reportedly detained in a flat in Nasr City, BBC reports.
According to the report, he has been accused of stirring violence and murder over the killing of eight anti-Brotherhood protesters outside the headquarters in Cairo last June.
A state of emergency was declared by the interim authorities after a crackdown on Islamists to clear the protest camps set up by supporters of ousted President Mohammed Morsi on Wednesday.
Almost 900 people, including more than 100 police and soldiers, have been killed in the turmoil and hundreds of members of the Muslim Brotherhood have been detained over recent days.
Meanwhile, Egyptian prosecutors have added a further 15 days to ousted President Morsi's detention for further investigating into fresh allegations against him.
