Imposters pretending to be child protection officers used fake IDs and asked to "check" on an Australian mum's babies.
A man and a woman knocked on the mother's door in Queanbeyan, New South Wales last week and asked to see her six-month old twins. The babies were asleep at the time, so the imposters waited in the woman's lounge until they woke up.
They spent a few minutes in the bedroom with the babies and then left the property, according to SBS News.
The woman felt uneasy and called the Australian Department of Family and Community Services, which had no record of the visit.
The woman and her family had never interacted with the department before.
She became distressed and called police, who are investigating the incident and have released computer-generated images of the suspects.
Detective chief Inspector Neil Grey said police had not received reports of similar cases, and were not sure of the offenders' motivations.
"Anything that involves children is always a concern," he said.
The woman is believed to be in her 20s with tanned skin and medium-length curly hair, and was wearing an orange blazer and dark-coloured skirt.
The man is believed to be in his 30s, a Caucasian with short dark hair and a prominent nose, and was dressed in a business shirt and trousers.
