The incident happened on Corner Perth and Fifth Avenue in Westdene in a passageway.
A close bystander said he just saw two women burning something.
“The woman were burning something with sticks and I didn’t know that it was a baby. When we went nearer we heard a cracking sounds like meat on a braai and eventually saw that it was a baby.
“We then immediately contacted the police."
The police are unsure whether the baby was alive or dead at that time.
