BISMARCK, ND - UPDATE 6:25:
Bismarck Police responded to reports of shots fired near the 1100 block of University Drive at around 6 a.m.
When officers got there, they found two men with outstanding warrants outside of a home and arrested them.
They also found nine small caliber casings in the street in front of a home that looked like it was shot.
Officers couldn't tell if there was still a threat, so they activated a shelter in place.
After making contact with the home's tenants, police learned some of them had outstanding warrants, so the officers took the tenants into custody as well.
Officers say no one was hurt and they're still investigating the incident.
