A Florida sheriff’s office has released dramatic body camera video showing a heroic deputy climb a three-story apartment building to rescue a baby during a fire.

Orange County Sheriff’s deputies responded early Saturday morning to the Isles at East Millenia apartments in Orlando after part of the complex caught fire, the sheriff’s office said.

"It was chaos everywhere," Deputy William Puzynski told FOX35 Orlando. "I started looking around you could see families trapped on each floor, hanging off the balconies."

Puzynski and other deputies saw a mother and her baby on a third-floor balcony as flames from the "raging" fire entered the apartment, the sheriff’s office said. 

The quick-thinking deputy took off his outer ballistic vest, which his bodycam is attached to, and began climbing up the outside balconies with some help from his fellow deputies.
