An investigation has been launched into a fire at the former Strathmartine Hospital on the edge of Dundee.
Fire crews were called to the derelict site on Friday after reports of a blaze within the premises.
Upon their arrival, firefighters found a pile of rubbish ablaze.
Three fire engines were sent to the scene at around 2.30pm.
No police are looking to hear from anyone who may have information in regarding to the incident.
A brief statement from the force read: “Police Scotland is appealing for information after a fire in the old Strathmartine Hospital at 2.30pm on Friday October 13.
“Scottish Fire and Rescue Service quickly extinguished the fire.
“Anyone with any information that may be useful should contact Police Scotland on 101 quoting CR/26759/17.”
Karen McAulay, a Strathmartine Hospital preservation campaigner, urged for action to be taken after a number of blazes have sprung up at the site.
She said: “A lot of the buildings are probably structurally sound enough to take the consequences of a fire but some of the listed buildings are a concern.
“There was still quite open access to the site last month so I don’t think they’re going to get it under control.
“Something has to happen – whether that is putting somebody up there full-time as security or something else but, at the end of the day, if you buy a site like that you have to make sure you have the money for security.”
The Tele previously revealed that the abandoned site has attracted ‘urban explorers’ with youngsters taking to social media and sharing images from inside the old hospital corridors.
The site is current owned by investment firm Heathfield Ltd who are looking to sell it on.
