Hundreds of employees of the Eastern Cape health department have been issued with final warnings aft.
Warrant Officer Xoli Mbele said the woman, 30, met the man she knew on Saturday at 2am, after she returned from a tavern.
"He forcefully took her to his flat where he raped her. He fell asleep and the victim ran to a police station," he said.
He said the police found him still asleep and he was arrested.
He was expected to appear in the Johannesburg Magistrate's Court on Monday.
