WESTMINSTER, Colo. — Investigators believe discarded cigarette butts started a fire at an apartment complex on Sunday morning, the Westminster Fire Department said.
Firefighters responded to the structure fire about 2 a.m. at the Copperwood Apartments at 8200 Sheridan Blvd.
Crews found light smoke and fire coming from the eaves of the third-story unit and were quickly able to knock it down, officials said.
They believe the fire started on the balcony when discarded cigarette butts ignited combustible deck materials.
Fire officials said no residents or firefighters were injured.
The fire did not spread to any of the adjoining units in the building, according to the fire department.
