Colorado firefighters rush to burning apartment building in Westminster early Thursday morning

Early Thursday morning, fire crews in Westminster rushed to a burning apartment building- twice. Firefighters rushed to the Village of Greenbriar complex near 83rd Avenue and Federal Boulevard shortly before midnight and then again about six hours later. 

The CBS News Colorado helicopter flew over the scene where flames were seen coming from the roof. This was reportedly the second fire in the same building within just a few hours on Thursday morning. 

Two Westminster police officers who responded to an earlier fire in the same building were treated for smoke inhalation while assisting with the evacuation of apartments, according to investigators. Both were treated at the scene; one was transported to the hospital and then released. 

"So actually, last night, shortly before midnight, the Westminster Fire Department received a report of a fire here at the Greenbriar apartments in building eight, we responded and extinguished the fire at that time," said Emily Raisch, Public Information Coordinator for the Westminster Fire Department.

Investigators said that no residents were injured in either fire. They have yet to determine whether the fires occurred in the same unit or were related. 

"So this morning, at around 6:30 a.m., we received reports of an additional fire here at the same building at the Greenbriar apartments. This time, we had smoke... flames coming from the roof," said Raisch. 

She said the fire was under control, but crews continued to extinguish hot spots throughout the morning.   

Investigators said people living in eight units in the building where the fire happened were displaced.  

What caused the fires is being investigated. Adams County Fire and Thornton Fire crews assisted Westminster in fighting the fire.
