This picture is slightly fuzzy because it is an enlargement, showing how the plain-clothes cop in the middle is holding the end of a baton which is hidden in his clothes.

The man on the left is Brigadier Schroeder. Next to him is Caroline Clark of the Sunday Times, and next to and slightly behind her is Larry Butchins of the Sunday Tribune. Later in the day both Caroline and Larry were arrested, and they had to endure a long trial, which ended with them each having to pay a fine of R50. In the middle is Prof Bozzoli, the Vice-Chancellor of Wits University. The man with horn-rimmed spectacles just behind Bozzoli's left shoulder is Adam Klein, who was a member of the Students Representative Council. Adam left South Africa four years later while the security police were looking for him hoping to hand him a banning order. The man on the right in a white T-shirt is Jasper Mortimer, who was arrested later that day. He became a journalist, and now lives in Turkey and reports for France 24.

By now Rand Afrikaans university students had gathered on the wall across the road. They shouted abuse at the protesting students. The wall was on the boundary of Lion Brewery. The two sticks in the picture are different to the batons that were used to bash students.

Brigadier Schroeder with a loud hailer. He was punished for trying to stop the police violence by being transferred out of Johannesburg soon afterwards.

A large number of uniformed police were brought to the scene later in the day to attack protesting students.

Glenn Moss addressing the students with a loud hailer. Uniformed police can be seen in the background. They only arrived to conduct attacks after a few rounds of attacks by plain-clothes police. Two people standing on something high in the distance to get a view of the attacks.

The three men in white coats are medical students. Many of them joined the protest after lectures, and the bigwigs at Wits Medical School reprimanded them for taking part in the protests.
