Demonstrating students on Wednesday set fire to a lecture room and vandalised the Tshwane South College, on the second day of protests at the Atteridgeville campus.
Three students were arrested for public violence.
On Tuesday, lecturers and other members of staff had to lock themselves in the institution’s buildings when hundreds of students went on the rampage over a lack of textbooks among other things.
Fire fighters doused the flames that ravaged one of the lecture halls at the campus.
It is understood the students returned to the building after an earlier fire had been put out.
The demonstrators locked the gates to their campus for the second time before vandalising buildings.
The fire brigade cut open the gates allowing police to enter the premises.
