OVERLAND PARK, Kan. -- Overland Park fire investigators are trying to figure out what caused an apartment complex to go up in flames Saturday.
It happened near 83rd and Wedd. Thankfully, nobody was hurt.
FOX 4's Molly Balkenbush was outside the complex where she spoke to people to a woman who was rescued from a balcony by firefighters.
That women was trapped on the second floor balcony with her dog.
She said she heard someone banging on her door frantically and she was scared it was an intruder so she locked herself in the back bedroom
It turns out it was her neighbor trying to warn her of the fire.
She was able to get out of that back bedroom and make it to her balcony where firefighters were able to use a ladder to rescue her and her dog.
Fire crews said four units in this building have smoke or fire damage and at least two can't be occupied right now.
FOX 4 spoke to that neighbor who frantically knocked on doors trying to tell people to clear out of the building.
She said she called 911 and was able to make it out safely with her dogs.
"I came back in and then I started to get scared because the smoke was getting so bad and it was hard to catch my dogs, which I know you aren't supposed to do that, and I got their leashes on them and got them out, but I wasn't going to leave them," she said.
Firefighters said the fire started in a bottom unit but they are still trying to determine what caused it.
They said the building had working smoke detectors.
The Red Cross will assist the displaced tenants.
