Grandmother held at gunpoint in mistaken robbery at Tambourine in Gold Coast hinterland

A grandmother was held at gunpoint when four armed intruders stormed her home demanding drugs in what police believe was a terrifying case of mistaken identity.

CCTV footage showed the men — armed with a sawn-off shotgun, a baseball bat, and a hammer —jumping the front fence at Tambourine, in the Gold Coast hinterland, in the dark on November 22.

“Smashed that window right in front of me and just within two seconds they were through that window and had the gun to my head,” the 61-year-old, who asked not to be identified, told 7NEWS on Sunday.

Her dog, Batman, tried to protect her, biting one of the intruders on the leg, but the attack did not stop the men.

“They were swearing at me and calling me, ‘where’s the f*** drugs’ — they clearly came for drugs and had the wrong house,” the victim said.

The intruders ransacked the home for about 40 minutes, before eventually realising the woman did not have the drugs they were seeking.

The grandmother said she still lives in fear in her own home.

“Not good at all. Can’t stay home by myself at night,” she said.

“I am scared in my own home, they took that safe space away from me — something like that changes a person.”

Before fleeing, the men poisoned her dog with food they left behind.

“He’s OK but he was spewing up everything the next day and I found chicken out on the ground with stuff all over it,” she said.

The intruders are believed to have left in a silver Chrysler, taking cash and alcohol with them.

The victim said she has received few updates from police in the six weeks since the incident.

“I just don’t want this to happen to anybody else,” she said, urging the public to come forward to help the investigation.

Anyone with information should contact police or crime stoppers.
