It happened at the Pines apartment complex near 12th and Alameda just after 1 a.m.
Firefighters received a call from nearby residents who saw smoke pouring from a downstairs apartment unit. When firefighters arrived on scene the kitchen of a downstairs apartment unit was in flames. They immediately began evacuating the building.
One resident did her best to warn other families.
"We were just worried that there were going to be little kids in the apartment and we started knocking on the door, for like a really long time and no one answered," said Soniya Kulkarni, a resident of the apartments. "By that time the entire building was smoked out and we could barely breathe, so we came up."
An Oklahoma City police officer was also injured in the fire. His injuries are not life threatening. The fire is still under investigation.
