Tens of students at the Cairo and Helwan universities protested Monday against police on campus as the Cairo University head renewed threats of expelling protesting students.

The protests were called for by student members in Ultras White Knights (UWK), the football fan group of the Zamalek club.

The group condemned a recent tragedy on 9 February as 20 club fans died when the police dispersed with tear gas a large crowd attempting to attend a football match.

While chanting anti-police slogans, the student lit fireworks as Ultras groups usually do in the stand.

The protests come only one day after head of Cairo University Gaber Nassar announced the expelling of 15 students.

Nassar said in a press statement that Cairo University will not allow students "belonging to the Brotherhood to disrupt the educational process and cause riots every now and then."

Some of these students, according to Nassar, set fire to state television cars that were waiting outside the university at the same time the prime minister was visiting.

"You have returned to violence and we have returned to expelling you for good," Nassar said, directing his statements towards students.

Some of these students were readmitted after being expelled, on the condition that they abandon protests, though many did not adhere to their promise.

In the 2013-2014 academic year, a total of 140 students were expelled from Cairo University but 52 have been readmitted.

Thousands of students have been arrested and stood trial in accordance with the protest law, while dozens of others have been expelled for their involvement in protests in the past few months as a result of the Supreme Council of Universities' decision to expel students and staff members involved in violence.
