An NYPD officer and five city firefighters suffered non-life threatening injuries Tuesday night due to a three-alarm blaze at a Brooklyn building.

"My sister called me. She was frantic. I came over here and I couldn't get on the block and I just saw the house on fire," said one man who lives in the building, who said his mother and sister are OK.

The fire started around 9:18 p.m. Tuesday night on the top two floors a three-story building that is on Bergen St. near Franklin Ave. in Crown Heights, according to the city fire department.

More than 135 firefighters were needed to get the fire under control by 11:51 p.m., the fire department said.

People nearby had been advised to close their windows and be mindful of the smoke and traffic conditions due to the blaze.

The cause of the blaze is not known at this time.

The fire department said one family, which consists of three adults, has been displaced.
