The demolition of a former Aberdeen school has been hampered due to fears over asbestos.
Contractors George Beattie and Son have torn down much of Kincorth Academy, which closed its doors for the final time last summer when pupils moved into Lochside Academy.
Demolition is expected to be completed by October, and the site has been earmarked for housing once the remains of the school have been cleared away.
However, works at part of the project ground to a halt yesterday after a report was made regarding an alleged asbestos find.
It is understood a member of the public raised the alarm.
A spokesman for George Beattie and Son stressed that work has only been stopped at the area in question, and will remain ongoing at other parts of the site.
He said: “We will investigate this allegation and stop works until any disputed actions are resolved.
“We went and reported it to our health and safety advisor, and we’ve also asked the Health and Safety Executive to get involved, in order to clarify it for all parties.”
Asbestos was found during works at Bridge of Don and Hazlehead academies last year.
However it has not been confirmed that the material is present at Kincorth.
Kincorth councillor, Alex Nicoll, said: “The health and safety of the workmen at the site and of local residents is of primary concern, and must be addressed as a matter of urgency.
“I also have concerns about the delays that may be caused by this, and any subsequent cost implications that may result due to this potential discovery.
“But first and foremost, we must be absolutely 110% sure that the site is safe for work to continue.”
A spokeswoman for Aberdeen City Council said: “An alleged breach of safe working practices by a contractor was brought to our attention and we took immediate action.
“We have suspended related works while an investigation is going on, and the works will re-commence once we are satisfied.
“The health, safety and well-being of our staff and contractors is of the highest priority.”
The recent report is not the first time the demolition of the school has been halted.
Tools had to be downed for weeks when baby gulls were discovered nesting in the roof in June.
TV wildlife expert Chris Packham was among those who commended the local authority for taking the step to ensure the protected animals were not disturbed.
When they flew the nest last month, work resumed.
