Police have defended their actions during the Fees Must Fall protest outside Parliament on Wednesday.
Officers fired stun grenades when students protesting high university fees stormed the National Assembly while the Finance Minster was delivering his medium-term budget.
Police actions were strongly condemned for their actions, with powers such the US government, voicing their concerns.
They insist, however that their actions are justified, adding they had little choice but to use force.
They do not believe they used unnecessary force, blaming the students instead for “constant provocation”.
Students had tried to push through the police barricade with their hands crossed above their heads.
29 students were arrested during the protest, six of them were detained overnight while the others, were released with warnings on the same day.
