A Queensland mum has shared the terrifying moment a stranger gave her kids biscuits as they played in the front yard in an attempt to lure them away from their Toowoomba home.

Stacey Alderman shared the footage, taken from CCTV the family has set up around their home, to a Facebook community group.

“Today on Luck St we had a man approach two of my children who were in the front yard, he watched and waited for no one to be around,” she wrote.

“Used grooming phrases, and gave my kids some sweet biscuits … Also: police are involved because of the nature of what he said.”

Ms Alderman’s sons, aged four and seven, didn’t take the bait and ran inside to tell their mum what had happened.

The boys told their mum the unidentified man had called them over to the front fence of their home on Tuesday afternoon.

Ms Alderman told The Chronicle the man offered her seven-year-old son a biscuit but warned him it was a “secret surprise”.

The man, who had waited until the coast was clear before approaching the two boys, was caught on camera fleeing the home when a car pulled up.

“(The stranger) told (her son) to keep the biscuits safe and that they were friends now because he gave them,” Ms Alderman told the publication.

“He said, ‘it’s our secret’.”

Police investigated the area after Ms Alderman’s complaint but failed to find the man.
