Police told NBC Chicago that the 911 caller told police that their daughter was being held against her will, and that the suspect was armed with a handgun.
A short time later, police located the vehicle on the Interstate and attempted to make a traffic stop. After pulling over, the suspect then fled the scene at a high rate of speed, and after officers observed what they believed to be the potential kidnapping victim in the vehicle, they initiated a pursuit.
The suspected exited the highway at Porter.
At least three Porter police vehicles were traveling in the southbound lanes at the time, with emergency lights activated, when they spotted the suspect’s vehicle driving directly at them. The first two vehicles were able to swerve out of the way, but the third collided with the fleeing vehicle head-on.
Two occupants of the suspect’s vehicle then got out, and a foot pursuit was initiated. One of the suspects was tased, and was taken into custody. A second suspect remains at-large, according to police.
The officer's injuries are expected to be non-life threatening.
