Emeline Essertel, 24, went on the run earlier this year after being released on bail by Cardiff Magistrates' Court on January 31.
The au pair, who is now thought to be in Clermont-Ferrand, southern France according to the Daily Mail, was arrested in January while working with a family in Llantwit Major, near Cardiff.
But despite her court case and further accusations of theft against her, Essertel has been posting pictures of herself having fun on Facebook, and telling friends that she has been partying in Dublin and Amsterdam.
Worse still, she is still offering her services as a nanny to unsuspecting families who could easily be fooled by her description of herself as a "lovely girl" who would like to work in humanitarian aid.
According to the Daily Telegraph, one advert on a website that she last visited about a month after missing her Cardiff hearing in March, stated: "It will be eight months since I returned to France to complete my nursing degree and I would [like to] go back to see other countries to learn new cultures and be able to speak English [as soon as] possible."
"We are pursuing all lines of enquiry in South Wales, London and France in order to trace her," a spokesman said.
However, the tale is bound to strike fear into the hearts of parents considering taking on an au pair or nanny to help with their children.
To avoid being taken in by tricksters such as Essertel, the Childcare.co.uk website advises parents to check that prospective nannies have a valid enhanced CRB/DSB check as well as accredited qualifications in childcare and a current paediatric first aid qualification.
At interview, it also recommends asking why the candidate prefers working as a nanny to working in a nursery, for example, how they deal with bad behaviour and what they see as the greatest risks to children of the relevant age, both inside and outside the home.
Finally, before hiring a nanny or au pair, it advises carrying out a thorough background check.
