Gardai are warning parent and toddler groups to be vigilant after a robbery in the north of the county.
Last week in Bray a woman entered a very busy playgroup posing as a parent with a pram saying her baby was asleep.
She interacted with the mums and moved around the room, then left early.
It was discovered when the woman had left that purses and mobile phones had all been taken.
Gardai say this is the same type of ploy used in the pubs and clubs across the country every week-end.
Gangs go into the busy clubs a rifle through bags and coats, while club goers are distracted.
