Firefighters have extinguished a fire at the derelict Strathmartine Hospital site on the edge of Dundee.
Three crews rushed to the former hospital after the alarm was raised at 6.30pm on Sunday evening.
Firefighters tackled “multiple seats of fire” to the rear of Ward 14/15 in the sprawling and dilapidated complex.
A police spokesman said it was piles of rubbish to the rear of the building, rather than the structure itself, that had been set alight.
Firefighters used breathing apparatus, a ceiling hook and hose reel jets to bring the situation under control.
All three crews had left the site by 8pm on Sunday evening.
Police attended to conduct enquiries into how the blaze may have started.
A Scottish Fire and Rescue spokeswoman said: “We received a call at 18:35 this evening.
“The fire affected one of the derelict buildings where there were little pockets of fire,” she added.
A Police Scotland spokesman said: “Some rubbish was set alight to the rear of Ward 14/15.
We received the initial call at around 18:30. It was reported to us initially. We attended, helping with enquiries as to the cause.”
The spokesman said he could not confirm reports on social media that neighbouring residents had seen two young men, and one young woman, running away from the site.
Monifieth and Sidlaw councillor Craig Fotheringham, Conservative, tweeted after the first reports of the fire.
He said: “Oh dear I really do hope not again and that if it’s the case our stretched emergency services stay safe.”
