Protesting students at Stellenbosch University have threatened to shut down activities on campus, reports EWN's Monique Mortlock.
The students staged a mass meeting on the Rooiplein and have been demanding that Rector Wim de Villiers engage them about their list of grievances.
A group of at least 400 students have been moving from building to building across campus, in an attempt to gain access.
But all the doors have locked and police have been barring the protesters from entry.
The peaceful protesters have been asked not to disrupt tests and other academics activities.
Police and private security guards remained stationed across campus.
