Around 11:10 p.m., the sheriff's office said, a deputy tried to stop an SUV for speeding on northbound Interstate 43 in the town of Saukville. The SUV sped up and fled, but the deputy did not give chase.
The SUV got off I-43 at County Highway H in the town of Port Washington, ran a stop sign and rear-ended a Port Washington police squad car that was parked on the on-ramp's shoulder. The Illinois men ran off across the interstate. After a short foot chase and K-9 help, both of them were arrested and brought to the Ozaukee County Jail.
The officer who was in the squad car when it was hit had minor injuries.
