Twenty-four "rioters" were arrested after students tried to storm the Al-Azhar University headquarters, according to an Interior Ministry statement.
Around 1,000 students belonging to the Muslim Brotherhood made the attempt on campus on Wednesday but security forces dispersed the crowds, the statement claimed.
Among the arrested was a Turkish national.
The university and its offices have seen unrest and clashes with anti-Brotherhood students in recent weeks.
Twelve students were also recently handed 17-year prison sentences for rioting.
