A smoky fire at the Roosevelt Apartments on County Street Tuesday night kept firefighters busy for about three hours.

The fire broke out around 6:30 p.m.

District Chief Steven Beaulieu tells WBSM News firefighters carried out two disabled residents, including one woman who lived in the apartment above the one on fire.

"The crew of Engine Six went in and physically carried that lady out of that building and into the lobby. And then, there was an additional person on the second floor that needed help getting out," said Beaulieu. "That person was carried out by the crew of Engine Four."

The District Chief said two people were transported to the hospital with unknown injuries.

He described the damage as extensive.

"The apartment was charred with smoke all the way down to the floor. The furniture in the living room was charred and burnt, and then there was smoke extension within the hallway," he said.

Three people were displaced by the fire. They were assisted by the Red Cross.

The cause of the fire remains under investigation.
