A fire forced six people from their Troy home on Sunday.

Fire broke out at about 4:40 p.m. at a the three-unit apartment building at 251 4^th St. The fire originated on the third floor of building, according to Troy Fire Assistant Chief Rich Cellucci.

Two people live on each floor of the building. Everyone made it out safely, Cellucci said. 

It took about 40 minutes to get the fire under control. The building is structurally sound but cannot be occupied due to smoke and water damage, he said.

No one was hurt. The Red Cross is helping a total of four people at this point.

The cause is under investigation, but Cellucci said it is not suspicious.

The Watervliet Fire Department and Watervliet Arsenal Fire Department assisted at the scene.
