Firefighters remain at the scene of a blaze at the former Foyle College junior school site in Derry.
Following the discovery of the fire on Saturday night the Duncreggan Road area of the city was closed as the Northern Ireland Fire and Rescue Service (NIFRS) got the fire under control.
The fire is being treated as deliberate and police are appealing for information and witnesses.
