Gauteng Health says it has asked the police to investigate the claims.
The matter was brought into the spotlight by DA Gauteng Shadow Health MEC, Jack Bloom, on Monday – saying workers at the health facility were worried that the incident could be swept under the carpet.
A male patient is said to have sexually assaulted a 16-year-old fellow healthcare user at the facility – raising concerns over safety.
“I want to reassure members of the public that the issue of safety at our public health facilities is a priority. We continue to work with law enforcement agencies to strengthen preventative and response measures,” says acting Health MEC Jacob Mamabolo, in a statement.
The Department says the rape survivor is receiving medical and psychological support. His family has also been counselled.
Bloom has said the rape is the 11th violent incident at the hospital.
Another patient was killed in May by a fellow patient.
