PORTLAND, Maine (AP) Fire officials in Maine are investigating a fire at the Portland YMCA that displaced 31 men.

The Portland Press Herald reports crews responded to the Portland YMCA around 4 p.m. Thursday. Assistant Fire Chief Keith Gautreau says a sprinkler system helped contain the small fire.

No injuries were reported.

According to a YMCA statement, the residents had been living in the dormitory through a housing support program called GROW. YMCA officials say the program provides temporary shelter for men moving into stable housing from homelessness.

YMCA of Southern Maine CEO Helen Brena says the organization is working with the Red Cross to help residents who have been displaced by the fire.

Officials say the YMCA will be open Friday.
