Officials say multiple crews battled a fire at Westbrook High school Sunday morning.
It all started after an extension cord was improperly plugged into a window air conditioning unit in the third-floor classroom wing, according to Westbrook Fire Department.
When officials arrived on the scene, they could see the smoke and fire coming out of the third floor and immediately contained the fire.
They said two sprinkler heads came on and kept the fire from spreading to the rest of the school.
