The MEC for Education in Gauteng Panyaza Lesufi rushed to Vanderbijlpark shortly after hearing the news of the tragedy.
A pastor held services Friday at the site of the collapse.
"I went to the rubble and was told that Roydon was still breathing and had a pulse".
"As the country mourns the loss of three lives of learners who tragically died at Hoërskool Driehoek, the BLF has spread some of the most vile sentiments", DA Youth leader Luyolo Mphithi said on Saturday. Unfortunately, the learners were walking under (the concrete slab) when it fell over them immediately after assembly. The state-owned South African Broadcasting Corporation reported that police are investigating.
When TimesLIVE visited the school, which has since been declared a crime scene, a small portion of the bridge was seen to have fallen.
The Minister of Basic Education, Angie Motshekga sent her condolences to the learners' families and the entire school.
Driehoek was inundated with mourners who hugged one another, lit candles and piled bouquets of flowers between the metal slats of the school gates.
"My heart goes out for the school because a lot of my friends were (there)", said one of the boys, Herco Lintvelt.
The department says that assessments of public buildings, including schools, are underway to make sure that this never happens again.
