They were later taken into custody. The driver of the vehicle fled the scene while opening fire on law enforcement during the pursuit. The suspect struck road spikes, eventually exiting Highway 26 at Highway 12 outside of Fort Atkinson.

No law enforcement officers were injured during the incident. An investigation is ongoing.
