Captain Jackson Manatha said the woman was asleep in a room with her grandson when a man entered at 11pm on Saturday night.
“The granny was stabbed on her upper body and she died instantly. The motive for the murder is not known at this point in time,” said Manatha.
“The suspect was known to the grandson and police arrested him the same night. The grandson was not injured and it appears that the granny was the target of the killing.”
He said a 35-year-old man was arrested on Saturday night. It was not known how he was related to the elderly woman.
The man would appear in the Willowvale Magistrate’s Court on Monday on a charge of murder. – Sapa
