Detectives have found no evidence that crimes took place at a nursery after a former member of staff admitted child sex offences.
Zara Lancashire, of Datchworth Turn, Hemel Hempstead, admitted making and distributing indecent child images and publishing obscene articles at a hearing in St Albans Crown Court on Wednesday.
Hertfordshire Police said it had spoken to more than 100 parents of children at Flower Pots Day Nursery in Kings Langley but all of Lancashire's offences "were committed online".
The 20-year-old will be sentenced on 5 March.
