(Fargo, ND) -- An early Thursday morning fire caused thousands of dollars in damages and left multiple people without a home in Downtown Fargo.

Fargo firefighters responded to a report of the blaze on the roof of an apartment building at 110 1/2 9th Street South at 12:01 a.m. On arrival, the fire was visible along the roofline of a single-story section of the building. Firefighters made entry into the building and found the fire had extended from the roof into the wall of an apartment in the second-story section of the building.

A second alarm was called because the fire had spread into the wall and roof area and it was hard to access. Crews began working to gain access to the fire from the outside on ladders, the inside of the apartment, and from the roof of the second story. Other crews performed a search and evacuated any residents that were still inside. The fire was declared knocked down after about 30 minutes.

There were no injuries to residents or firefighters. Two residents who lived in the apartment affected by the fire were displaced. The Red Cross assisted them with temporary housing. The other residents were able to return to their apartments after the fire was extinguished.

The cause of the fire is under investigation. The initial estimate for the damage is $30,000.
