The tyre inferno at an industrial site is now not thought to be suspicious, the police have said.
Fire chiefs initially believed the blaze at Piper Street in Whitfield on Monday was started deliberately because it was “unlikely” one of that nature could have started on its own.
However, police have now poured cold water on the theory, saying there are no “apparent” suspicious circumstances surrounding the incident, despite the presence of a gang of youths nearby at the time.
Emergency services were first alerted to the blaze by a member of the public who spotted black smoke rising from the area at about 8.30pm on Monday.
Firefighters battled through the night and into the next morning to control the flames.
Police also had to attend the scene to prevent the gathered crowd watching from getting too close.
There were also concerns that the water used by the firefighters may have caused damage to the area and the Scottish Environment Protection Agency was called in to survey the site.
A spokesman from the agency said: “Following a thorough inspection by SEPA officers, it was established there was no significant impact on the local environment and no run-off water from the fire had entered into local watercourses.”
