BUFFALO, N.Y. - Buffalo Firefighters responded to a two-alarm fire in the city's Allentown neighborhood Sunday morning.

The fire started in a residential building near the corner of Franklin and Allen Streets around 8 a.m.

Buffalo firefighters tell 2 On Your Side there were four occupied apartments at the time of the fire. Two people were rescued from a second-floor window.

Fortunately, no one was hurt.

Barry Rebholz's girlfriend woke him up this morning in a panic and he says he knew immediately something was terribly wrong.

"I open my apartment door, and I looked up at the top of the stairs and the fire was roaring out of the back of the apartment. I mean I couldn't even see the wall, I couldn't see the door, flames were just roaring out," Rebholz said. "And the girl that lives across the hall, that was her only door, her entire door was engulfed in flames."

Saturday afternoon Buffalo Police tweeted that they have an individual in custody in connection with the fire.

A 29-year-old man has been charged with arson.

Fire crews were still working on putting out hot spots more than two hours after the fire started.

"This one was a very difficult fire because it is a cut up building, a very odd shape and an older building," explains Buffalo Fire Department Battalion Chief Tom Meldrum.

The Buffalo Red Cross says its volunteers are helping five to 10 people who were affected by the fire.

Rebholz said he lost basically everything in fire. His family started a GoFundMe page to help him rebuild.
