Police investigating two fires in Aberdeen say they are treating them as suspicious.
Both blazes broke out on Bonfire Night in the north of the city.
Grampian firefighters were called out to a blaze at Stoneywood Mill Sports and Social Club at around 2.30am on Saturday.
Less than four hours later, they were at the scene of another fire at the nearby Bankhead Academy, on Bankhead Avenue.
Grampian Police officers say they are keeping an open mind over whether the two fires are linked and are appealing for witnesses.
Neither building is in use and it is understood that nobody was injured.
Stoneywood Road was shut while fire crews tackled the blaze at the derelict sports centre.
A joint investigation is taking place to establish the cause of the fires.
