Two 15-year-old suspects believed to be involved in the murder of a Mondeor High School learner were arrested on Thursday morning, police said in a statement.

Mathebula, aged 19, was fatally stabbed on Wednesday on his way to school. He was a grade eleven student.

“The suspects were arrested in Soweto and Naturena … which brings the total number of arrested suspects to three within 24 hours,” South African Police Services spokesperson Kay Makhubela said.

On Wednesday police had revealed a breakthrough with the arrest of the first suspect, a 13-year-old pupil.

Makhubela said a team of detectives followed up information from the scene, which led them to another school in Mondeor attended by the 13-year-old suspect.

Gauteng Provincial Police Commissioner, Lieutenant-General Elias Mawela, welcomed the arrest of the suspect within 24 hours and condemned the killing of Mathebula. Mawela urged the community to work with police to trace the remaining suspects.

“The two outstanding suspects are suspected to be schoolchildren as well. Police are calling for the boys to hand themselves in because the police will not rest until they are arrested.”

Those with information about the whereabouts of the suspects were urged to call their nearest police station or crime stop on 08600 10111.
