Complaints about employee misconduct
Filing a complaint of misconduct:
Complaints of misconduct may be filed with local commanders or with Internal Affairs at MSP Headquarters.
Making a report locally:
Members of the public are encouraged to contact a local supervisor or commander by going to or calling the nearest state police post or district headquarters. Locations and phone numbers can be found on the District and Post Directory Page. Some complaints can be appropriately resolved by the supervisor. Those not resolved will be referred to the Internal Affairs Unit, who will contact the person making the complaint.
