At one point in the day troopers opened a secure door at the Romney building, where Gov. Rick Snyder has an office. Members of the crowd tried to follow troopers into the building but the officers used O/C spray, a form of pepper spray, when some of the crowd refused the troopers' commands. State police arrested two people who breached the doors.

Later in the afternoon a third person was arrested for refusing to comply with troopers at the Romney building, named after former Michigan governor George Romney.

Troopers also responded to a few minor calls for medical assistance but there were no major injuries or medical emergencies reported to MSP.
