TWO youths climbed onto the roof of a high school to start a fire and then watched from nearby as firefighters put out the blaze.
The fire has caused "significant damage" to the roof and top floor of Woodfarm High School in Thornliebank, East Renfrewshire.
No one was injured in the blaze, which started at around 10.30pm on Friday, February 17.
Police are appealing for information about the incident, which was captured on CCTV.
Detective Constable Stephen Walker of Govan CID, said: "The youths are seen on CCTV climbing up the side of the building and then on to the roof where they deliberately start a fire.
"They are then seen on Robslee Road, where they are joined by another male, watching the fire service attend to put out the blaze.
"There are a number of homes near the school, thankfully, not affected by the fire, but it may be the case that neighbours saw the youths on the roof or hanging about the area either prior to or afterwards."
The suspects are described as white, between 15 and 18 years old and wearing dark clothing.
One is believed to have been wearing a grey hooded top.
A message on the school website says it will be open as usual on Monday.
Why are you making commenting on The Herald only available to subscribers?
It should have been a safe space for informed debate, somewhere for readers to discuss issues around the biggest stories of the day, but all too often the below the line comments on most websites have become bogged down by off-topic discussions and abuse.
