LOS ANGELES (CBSLA.com) — Crews Wednesday extinguished a fire that erupted in an apartment building in Hancock Park.

Around 12:30 a.m., firefighters were sent to a two-story apartment building located in the 500 block of Rossmore Avenue, according to the Los Angeles Fire Department.

Upon their arrival, heavy smoke was showing from the attic.

A woman was assessed at the scene for possible smoke inhalation. She declined transport to a hospital.

Unfortunately, a dog died in the blaze.

Firefighters tore a hole in the roof to let smoke escape from the attic. No other units sustained damage in the fire.

Officials said the incident does not appear to be suspicious.

It remains unclear if smoke detectors were working in the unit when the fire erupted.

The cause of the blaze remains under investigation.
