A two-alarm fire in Bushwick closed down multiple streets Thursday night as the fire department worked to fight the flames.

Fire officials tell News 12 that the building where the fire started was undergoing renovations. Thankfully, no one was inside when the flames broke out on the third floor. However, they say that it didn't stop the fire from spreading from that building to the next.

Flames were seen billowing out from the window around 5:30 p.m.

Neighbors tell News 12 that the unit had been unoccupied for some time, but that new families and renters have moved into the buildings next door.

Firefighters say they were on the scene within three minutes of receiving the 911 call.

News 12 is told that there were minor injuries to firefighters. No civilians were hurt after all tenants in the neighboring apartments were evacuated.

Officials say they're deeming the fire suspicious. They say the investigation into the cause is ongoing.
