VIDEO: Firefighters battled a large fire at a vacant mill building in Naugatuck Monday night and demolition crews have begun to knock it down.
Officials said the fire started just after 6 p.m. Monday in the area of 200 Water St. and flames were found coming from the roof of the building, which is actually five separate buildings that are connected.
It's believed no one was inside because the building, which was once occupied by Lewis Engineering, has been vacant since around 2012. Aircraft parts were made there and the building was being used for some sort of storage, officials said Tuesday.
Clouds of heavy smoke billowed from the building Monday night.
The amount of smoke that carried out of the building was a concern, prompting officials to evacuate some nearby homes.
