Just after 3 a.m., Indianapolis Fire Department firefighters were dispatched to the 2400 block of Appleton Drive on reports of a structure fire.

When firefighters arrived at the scene, they saw heavy smoke and fire coming from a unit on the second floor.

A man sleeping inside the home said he was startled by the sound of a smoke detector. Investigators said he was able to get two girls out of the apartment, but when he ran back in to get two boys, he fell and hurt himself.

According to officials, a woman inside the home was able to get the two boys out by dropping them out of a second-story window to people waiting below on the first floor of the apartment.

The woman was able to escape through the window, officials said.

IFD said the cause of the fire was under investigation.

All six people were taken to St. Francis Hospital, but their conditions were not immediately released.
