The woman, 80-year-old Ana Bristowe-Lamb suffered a number of injuries including a large gash to the head which required six stiches and two bruised eyes.
Ms Bristowe-Lamb told police that she apologised to her attackers during the ordeal for not having money on her.
In what appears to be an act of remorse, the trio then handed Ms Bristowe-Lamb her phone to request an ambulance and offered her a glass of water.
Sergeant Oldfield said the trio likely were not targeting an elderly person and broke in unsure of who resided in the home.
There seems to be some sort of remorse at the time from the people responsible. It is unusual, this indicates it is not a targeted attack against the elderly,” he said.
“I think maybe they’ve been confronted by what they’ve discovered when they went through the door.”
The three teens are yet to be charged over the attack.
