Sinkie Madiba (69) was reported missing by his brother, Solomon Madiba, at the Germiston Police Station, on May 12.
Solomon told police that Sinkie had been visiting him from Hammanskraal and had stayed with him.
On May 11, Sinkie packed his clothing into a red plastic bag and left the shack where they were staying in the Goodhope informal settlement.
Solomon is concerned about Sinkie, as he alleges that Sinkie is mentally challenged.
Hospitals and even mortuaries have been visited but, thus far, there is no sign of the missing man.
He was last seen wearing a khaki shirt and navy blue jeans.
His head is shaven bald.
Anyone with information can contact Solomon on 074 756 7559.
Lieut-Col Andy Pieke, from the Germiston SAPS, can also be contacted, on 011 871-5037, or contact the National Missing Persons Bureau on 08600 10111.
