A paraplegic man shot and killed his gardener after the man attacked him in his Cradock home in the Eastern Cape, the Beeld reported on Monday.
Police spokeswoman Captain Stefanie Smith said the victim (58) heard a knock at his door and opened it, as he had been expecting a relative on Saturday morning.
His gardener forced his way into the home, threatened him with a knife and demanded money, the paper reported.
The victim was stabbed in both arms, then wheeled into his bedroom, where he was further assaulted.
When he fell out of his chair, he managed to reach his rifle, which had been positioned next to his bed.
He fired one shot at his assailant, who was critically wounded and later died at the scene.
Smith said a murder docket had been opened.
