An investigation has been launched after a major blaze ripped through a disused Dundee factory at the weekend.
The aftermath of the fire, which took firefighters four hours to extinguish, left the building substantially damaged.
The derelict building on Forties Road can be seen from nearby residential street Montpellier Gardens.
Firefighters returned to the scene on Saturday morning and spent an hour making sure the building was safe and no hot spots remained.
A spokeswoman for the Scottish Fire and Rescue Service said: “It was a derelict factory on fire and we sent three pumps in total.
“The first was on the scene at 9.54pm and left at 2.22am. The building was about 30 by 15 meters and two storeys high.
“Crews used four sets of breathing apparatus, two jets and a thermal imaging camera to bring the fire under control.”
She said crews had used a sectional approach to bring the blaze under control, with some firefighters keeping the fire at bay while others closed in to reduce and finally extinguish the flames.
She added: “Crews were back checking for hot spots at 8.56 on Saturday morning and left at 9.52am after confirming the area was safe.
“The incident has been passed over to the police, who were also in attendance.”
The incident is one of a number of suspicious fires to have taken place in derelict buildings in recent months.
A major blaze in April engulfed the former Strathmartine Hospital and, more recently, the former Keiller’s sweet factory on Main’s Loan was also targeted.
As previously reported in The Courier, fireraising costs the city £1.25 million a year around £2,000 per hour for every incident.
The fire and rescue service has issued warnings, particularly over the warmer months, of the consequences of deliberately setting fires. Parents have been urged to ensure their children know about and understand the potentially tragic consequences deliberate fires can have, as well as the impact for the responding emergency services.
