The Fargo Fire Department says the roof has collapsed on a commercial building in the city.

According to the department, the building, located at 3301 13th Avenue South, had been deemed unsafe earlier this week after it was discovered that the roof was sagging and the beams under the roof were buckling.

Sometime during the night Wednesday into early morning Thursday, the roof collapsed, the department said.

The department was called to the scene originally on Tuesday.
