Detectives are treating a fire at a former Aberdeen school as deliberate.
This is the second time Cordyce School, just off Riverview Drive in Dyce, has gone up in flames in the past three years.
The derelict site, which was severely damaged following a vandal attack in 2017, was targeted again at around 9.50pm on Friday night.
The Scottish Fire and Rescue Service sent a number of appliances to tackle the blaze.
The roads in the surrounding area were closed off, but have since reopened.
Police are now treating the fire as wilful and want to track down a group of youths seen in the area at the time of the blaze.
Detective constable Stuart Hache, of Aberdeen CID, said: “Thankfully no one has been injured as a result of the fire, however we are now treating the fire as wilful.
“We are still appealing for anyone who has information and are especially keen to speak to a group of youths who were seen in the vicinity at the time of the outbreak of fire.”
