Fire crews were called to fire in an underground parking structure at a Middleton apartment complex early Tuesday.
The fire began just before 8 a.m. at Brittany Apartments on the 1200 block of Sweeney Drive, according to the Middleton Fire Department.
Fire officials said a car started on fire, forcing the building to be evacuated. They said the fire was contained to the basement, but the entire building, which is more than 20 units, suffered smoke damage.
Several cars were damaged in the fire, but officials said it is too early to estimate the total damages.
"We were informed that there were people potentially still inside the building. We were able to assign search crews, who cleared the structure. We did find a few people inside, and we were able to get them out safely," said Chief Aaron Harris, of the Middleton Fire Department.
Nobody was hurt in the fire. Numerous pets were rescued by firefighters, fire officials said.
