Daqahliya security forces managed to disperse a protest staged by a number of Muslim Brotherhood (MB) students at Azhar University branch in Mansoura.
Also, four students were arrested during the protest's dispersal.
Earlier, dozens of MB students staged a demonstration, which roamed the university campus in protest of the acquittal of former president Hosni Mubarak from several charges.
The students also chanted slogans against the army and police, raised pictures of their detained colleagues and demanded their release.
They also pelted security forces with stones and threw fireworks toward them.
