Fire marshals say an electrical problem in a building's wiring caused a fire in an apartment in the Bronx on Wednesday morning that led dozens of people being displaced from their homes.

"I only grabbed my wallet and my ID. That's it. When you smell smoke and everyone's telling you to evacuate," resident Amanie Gabrielle said outside her building after the fire. "My cat is still inside. I have nothing right now."

Officials are ruling the electrical problem accidental.

Investigators said the blaze started in the cockloft of a six-story building at 3414 Knox Place in Norwood around 4:20 a.m.

More than 150 firefighters responded to the scene. Two people suffered minor injuries in the four-alarm fire.

The Red Cross said 37 apartments in the building have been vacated, and it is working to relocate more than 70 people.

The fire department said the apartment had a smoke alarm but it was not working.

There was another big fire in nearby Belmont.

One person was hurt in that blaze but refused medical attention.

The cause of this fire remains under investigation.
