A fire at a Bronx apartment building left at least 22 people injured Tuesday night.

The fire on the second and third floors of the building on Baychester Avenue saw the response of authorities at just before midnight, per CNN, with more than 100 firefighters ultimately arriving on the scene for assistance. 

"We're all proud of the NYPD 47th Precinct cops who rushed into a Bronx apartment building that was on fire last night and rescued residents," Chief Terence Monahan said in a statement. "Thankfully, nobody was seriously injured."

Ultimately, nine people were injured, five of whom were taken to a nearby hospital while the other four refused transport. Additionally, 13 officers were treated for smoke inhalation. Of the patients taken to the hospital, four suffered minor injuries and one has injuries described as "serious."

Resident Harold Bonet, speaking with a local NBC outlet, said he saw "flames gushing out." As of Wednesday morning, the cause of the fire—which was confirmed as being "under control" within an hour of authorities’ response—was still under investigation.

Back in October, a five-alarm fire on the roof of another Bronx apartment building caused serious injuries and took more than three hours to get under control. Of those injuries in the six-story building fire, two—including one firefighter—were reported at the time as being serious.
