A nursery worker has been arrested and charged over the possession of indecent images of children.
The man, who has been suspended from his post at a Oranges and Lemons nursery at Technology Park in Dundee, was detained by officers on Tuesday.
On Monday Tayside Police confirmed the 20-year-old man had been charged.
A spokeswoman for the force said: "Thorough and meticulous police inquiries are continuing to establish the full circumstances around these matters. These investigations include the forensic examination of computer equipment.
"Tayside Police and its partners are acutely aware of the concern generated within the community when people become aware of alleged offences of this nature. While acknowledging the urgency of such concerns, it is important that the investigation is given the time and space it requires to ensure that all evidence is gathered and reported in full to the procurator fiscal for consideration.
"Tayside Police, and the education and social work departments of the three local authority areas in the region, as well as care providers, are working closely to ensure that the appropriate information and support is in place for any families and children closest to these allegations."
A spokesman for Oranges and Lemons Nurseries said: "As a care organisation driven to delivering the highest standards in child care, the allegations against a member of staff from Technology Park Nursery have come as a great shock to us.
"The safety and welfare of children in our care is of the utmost importance and all staff undergo enhanced PVG checks as part of our rigorous recruitment policy. The member of staff in question has been suspended with immediate effect and we continue to co-operate fully with the police throughout their investigation.
"We also continue to communicate with all parents as we meet our objective of providing a safe and secure learning environment for their children."
