Durban - Health MEA hospital worker was shot dead at the King Edward VIII Hospital, in Durban, on Thursday, the KwaZulu-Natal health authorities said.
MEC Sibongiseni Dhlomo said the victim was rushed to an operating theatre, but attempts to save him failed.
The name of the dead man could not be released as his next-of-kin had all been informed.
Speaking at the hospital on Thursday afternoon, Dhlomo said he could not comment on the circumstances of the shooting, as it was subject to a police investigation.

A large sign prohibiting firearms was displayed outside the main entrance, next to the security office.

Police spokesman Captain Thulani Zwane said: "The alleged gunman is on the run; police are looking for him." - Sapa
