INDIANAPOLIS — An early morning fire at a near northwest side apartment complex sent one person to the hospital and led to the evacuation of about 50 people, and IFD says the person who lived in the apartment where the fire started alerted her neighbors by pulling a hall alarm on her way out of the building.

Crews were sent to the El Dorado apartment complex off of W. 21st and N. Tibbs Avenue shortly after 3:30 a.m.

Firefighters reported seeing heavy flames from a four-story building with 40 units.

IFD had to use ground ladders to rescue 12 people from all four sides of the building. About 50 people were evacuated total.

“Pretty scary moment for all these people because they were sleeping,” said IFD’s public information officer Rita Reith.

She says the fire was contained to the one apartment, however the entire building filled with “high levels” of smoke.

The woman who was living in the apartment where the fire started told crews she had electrical issues for some time and reported them to management on several occasions. She said she was woken up by the sound of her portable fans turning off and then noticed a fire near an outlet in the bedroom.

Firefighters say the woman was able to escape with her three children (ages 3, 6, and 7) and a chocolate labrador puppy.

They say the family lost everything in the fire.

Officials say the fire did not spread to any other units because the apartments’ exteriors are made of concrete.

One person was taken to a local hospital to be checked out for smoke inhalation.

Fire investigators say the fire was accidental and was caused by an electrical failure of a floor receptacle next to the bed.
