Seven people were hospitalized and several people -- including a firefighter -- were treated on scene after a massive fire broke out at a Paddock Hills apartment complex Sunday night, according to authorities.
The fire reportedly originated on Park Lane Apartments' third floor, but first responders said it spread to other floors and smoke damage was extensive in some apartments.
Crews put out a mayday call after a firefighter's mask became dislodged, Cincinnati Fire Department Chief Roy Winston said.
"They got him into the stairwell, he was treated on the scene," Winston said. "He's been released back to duty as well."
Chief Winston said the fire spread down the hallway and quickly spread to other apartments. He estimates they rescued about 20 residents, transported seven to hospitals and treated six more on the scene.
