A fire damaged an apartment building in Westwood this morning, but no one was hurt, authorities said.
Firefighters sent to the 10600 block of West Wilshire Boulevard at 4:37 a.m. doused the flames in the five-story building in about an hour, said Los Angeles Fire Department spokesman Brian Humphrey.
The building, about half a mile southeast of UCLA, was equipped with smoke alarms that alerted residents to the fire, Humphrey said.
"It's surprising," said Larry Link, manager of the Princess Apartments, about waking to the sound of a smoke alarm. Link was in the building when the fire broke out.
The cause of the fire is under investigation. Link said that most of the residents have been able to return to their units.
"They're all being taken care of," Link said about the residents. "The Red Cross was here."
Cost of the damage to the 56-year-old Princess Apartments building is estimated at $170,000, according to the LAFD.
