2 in custody following chase after Police Officer hit during traffic stop

Two people were being questioned by police after the car they were in ran down an officer who was trying to make a traffic stop late this morning.
Officers made a traffic stop near 75th and State streets about 11:10 a.m. and the driver of the vehicle "used the vehicle as a weapon" and hit one of the officers. The officer was injured and treated, but the injuries were not believed to be life-threatening.
One of the officers fired shots, but no one was hit.
The vehicle then was driven off, leading police on a chase that ended near 78th Street and King Drive, where the two people were taken into custody.
Police were investigating to determine if both people from the car or just the driver should be charged in the incident
