Pretoria - The Economic Freedom Fighters Student Command shut down proceedings at the University of South Africa's Sunnyside campus on Friday morning.
Students from the ANC Youth league clashed with EFF students claiming that their shutdown was uncalled for.
Workers of the university were told to stop working and close the doors.
Scores of police officers roamed around the streets to maintain the situation as traffic was backed up.
The EEFSC claimed that the university has not been assisting students with registration and turned more than 500 students away since Wednesday.
