On September 21, 2018, Officer Matthew Christensen participated in the arrest of Spencer Erickson. During the incident, a police dog bit Erickson’s neck, and Christensen restrained Erickson’s extremities, leading to severe injuries. A federal judge permitted a lawsuit against Christensen and other officers to proceed, citing possible excessive use of force.
