Firefighters extinguished a fire that broke out on the ground floor of a multi-story building in downtown Los Angeles Monday morning.

The fire erupted shortly before 8:30 a.m. at 255 S. Grand Ave., inside a restaurant that had been undergoing renovation, according to the Los Angeles Fire Department.

Fire officials said they received unconfirmed reports of a possible explosion in the kitchen.

The flames were contained to the restaurant, but smoke traveled up through the building and was seen faintly billowing out the top.

There were reports of people stuck in the elevators of the 27-floor high rise.

“While this is at a Major Emergency status, the fire is extinguished and the incident is in the search and rescue phase,” LAFD said around 8:50 a.m.

Firefighters were recalling all elevators in the building and looking for anyone who may be stuck.

About 60 people ended up getting evacuated from the high rise, which has 391 residential units home to more than 700 people, according to the Fire Department.

One person with burn injuries was rescued from inside the restaurant and taken to a hospital. The person, whose condition was unknown, had been working on the restaurant renovation.

Another person, a woman, was also taken as a precaution due to smoke exposure, officials said.

At some point, officials said they were concerned about evacuations, since the building is large and has many occupants.

Arson investigators were called to the scene.

Officials said the fire will significantly impact traffic, and asked residents to avoid the area.
