Mandan Police and the Mandan Fire Department confirm that there were reports of a woman with a gun inside an apartment on Third Street in Mandan.
The woman left the scene before law enforcement arrived.
There also was a call of a fire in the basement of the building at the same time.
Police say it's unclear if reports of the fire and woman with weapon are related.
Police had to clear the building before fire fighters could enter and extinguish a burning rug in the basement.
