LAFAYETTE, Ind. (WLFI/CNN Newsource/WKRC) - New body cam video is painting a more clear picture of what one Indiana man went through to save children he didn't know.

Nick Bostic, a pizza delivery man, was driving by around 12:30 a.m. on July 11, when he saw a house in flames and jumped into action. According to a police release, Bostic opened the back door of the house to alert anyone inside. Despite not receiving any answer, he went in, made his way upstairs and found a group of children sleeping.

Bostic rescued four children, ranging from ages 1 to 18 -- three of whom were siblings and one friend who was spending the night.

"I told them to get out and they followed me down the stairs and out the house, and at the back door I asked if there was anybody else left, they said there was a child in there," the 25-year-old said.

Bostic ran back inside the burning home, now so black he could not see anything. He told police that he crawled on the floor, feeling in front of him, and listened for cries to find a six-year-old child. Once the girl was found, they had to exit through an upstairs window.

"I did try to find the back door, but I couldn't find it and I didn't want to get too lost," Bostic said.

With the child in his arms, Bostic jumped from a second-story window, landing on the side where he was not holding the child. Bostic sustaining multiple injuries, but the girl was mostly uninjured, according to a police release.

"The front of my hand, it's cut up pretty bad. They rewrapped it before I left," said Bostic, who was flown to Indianapolis to receive treatment. "But I got a cut right here, a possible severed tendon. The bottom of my hands are blistered like I grabbed something hot. I recall seeing flames through the window as I was punching it out."

Along with that, he also had scorching in his throat and said doctors has to remove a good amount of soot from his lungs. But Bostic is just happy he was there to help that night, The parents weren't home at the time.

"This temporary pain, oh yeah it's so worth it, it's worth every bit," he said.

Bostic is still nursing injuries he sustained when he entered a burning house.
