Police have charged a woman with child stealing, swooping on the alleged fake au pair while she was with two kids at a shopping centre.
A mysterious au pair is behind bars accused of stealing children and faking documents to gain work.
Samantha Azzopardi, 31, was arrested at Pall Mall in Bendigo about 1.30pm on Friday.
She was located with two girls who are aged four and 10 months.
"It's alleged the woman forged documents to gain employment as an au pair," Victoria Police said in a statement on Sunday.
