Pretoria - Two doctors, a nurse and a security guard have since been put on special leave pending an investigation into the incident at Mamelodi Day Hospital this past week.
This was revealed by the new Health MEC Dr Bandile Masuku who met with the Marais family on Sunday afternoon.
The investigation is into why Martha Marais, 76, was restrained under a bench and made to lie on a floor at Mamelodi Hospital earlier this week.
Masuku added that the preliminary report indicated that Marias was restrained for more than eight hours.
Asked why the sickly Marias, was cuffed under the metal benches, Masuku said according to the preliminary report an incident had occurred that prompted the medical staff to tie her up.
