He has also commended the provincial police commissioner of Limpopo, Lieutenant General Nneke Ledwaba, on ensuring that the alleged killer of four children was arrested within a few hours.Ledwaba, who also visited the scene, condemned the incident in the strongest possible terms, "more so as it was allegedly perpetrated by someone who was supposed to protect these victims".Sitole also condemned the murders, saying the community has to take a stance against crimes against women and children.
