A 72-year-old woman living on her own shot and killed an intruder in St Francis Bay after she was tied up and threatened, Eastern Cape police said on Sunday.
Two men broke into her house through a window at 03:00 on Sunday and confronted her with a knife and screwdriver, spokesperson Marianette Olivier said.
She was blindfolded, tied up and forced to tell the men the pin numbers to her bank cards.
"While one of the men left with her car to draw money from her account, she managed to untie herself and got a firearm from the cupboard.
The man tried to grab her .38 Special and she fired shots, killing him. The second man came back, saw her standing with the gun and ran away."
A case of murder and house robbery was opened.
"No one has been charged with murder. We will do formal investigations, send a docket to the public prosecutor and then a decision will be made," she said.
