A police chase on Interstate-40 has led to an arrest. Coconino County Sheriff’s officials say an officer noticed a vehicle on the highway with a suspended license yesterday west of Flagstaff. When the officer tried to pull over the vehicle, 44-year-old Aaron Aulback of Flagstaff kept driving. Finally after a brief chase he went off the highway, went through a guardrail between the A-1 Mountain and Flagstaff Ranch Road exits and down a hill coming to a stop. As the officer approached the vehicle, the driver got out and tried to confront the officer with a spray can he had lit on fire. After a brief standoff the suspect was taken into custody. Aulback was booked on a slew of charges related to the incident, including aggressive DUI. There were no injuries to the officer or suspect.
