A fire broke out early Tuesday inside a seven-story building at UCLA's Westwood campus, authorities said.
The blaze was reported at 1:31 a.m. in Building 48A of the School of Dentistry, 714 Tiverton Ave., said Los Angeles Fire Department spokesman Brian Humphrey.
Nearly 115 firefighters knocked down the blaze around 2:15 a.m., Humphrey said. Crews were able to contain the fire to a classroom and office area. No injuries were reported and no faculty or students were threatened by the fire.
Investigators were working to find out what may have started the fire. A damage estimate was not immediately available.
