A councillor has said parents must take action if they suspect their children have been involved in fireraising.
Police believe a blaze in the former St Vincent’s RC Primary School on Pitkerro Road was started deliberately.
Teenagers have also been charged in connection with two other blazes in the city that are alleged to have been started on purpose, at Braeview Academy and the former Hilltown Indoor Market.
Lochee councillor Alan Ross, the convener of the city council’s public protection and community safety committee, said it was lucky no one had been killed or injured.
He said: “I would imagine parents must have noticed the smell if their children have started a fire.
“These people are putting the emergency services under severe pressure and they are obviously putting themselves, and potentially others, into extremely dangerous situations.”
