2 hospitalized, 3 treated at scene following large apartment fire in Fort Worth, officials say

Two people were transported to the hospital, and three, including a firefighter, were treated for smoke inhalation after an apartment building caught fire early Tuesday, officials say. 

FWFD said at about 5:30 a.m., crews were called to the two-story apartment building in the 6700 block of Calmont Avenue.  Firefighters helped residents get out of the building, as crews shifted to a defensive battle against the fire and called for additional crews as the blaze grew. 

FWFD spokesperson Craig Trojacek said two residents and a firefighter were treated at the scene for smoke inhalation, while two other residents were taken to the hospital for smoke inhalation. 

Trojacek said at least 50 units have been affected in the fire, displacing about 100 residents.
