Police investigators say a 73-year-old grandmother tried to stop a robbery at her home last night.
The woman and her 28-year-old granddaughter were returning to their Flanning Street home when officers say a man jumped out from the bushes and tried to force his way into the home.
Investigators say the grandmother tried to ward off the suspect with a knife, but the man grabbed it and hit the granddaughter in the head.
She suffered minor injuries.
The masked man made off with cash and fled on foot.
