Vusi Mahlanga from Pan Africanist Student Movement of Azania (PASMA) said it was an “unfortunate incident”.
Mahlanga said students are unhappy because of the proposed increase of 10% in university fees. They are also demanding that the institution drops all charges against student leaders.
According to Mahlanga, student leaders have been subjected to disciplinary hearings after the protest action in February this year.
Students are also demanding free accommodation and according to TUT’s spokesperson Willa De Ruyter some are demanding more financial assistance from the National Student Financial Scheme (NSFAS).
De Ruyter said that all activities on the main TUT campus have been suspended for the day.
“We will keep the TUT community informed,” she said.
Police were on the scene.
