Suspect: Troy Riley, 28, of Des Moines

A 28-year-old man is in custody after a high-speed chase early this morning through Des Moines. 

Des Moines police spotted a speeding red S.U.V. on the freeway and gave chase. Once the vehicle was pulled over on a city street, though, the driver gunned the S.U.V. at an approaching officer and the cops at the scene fired back.

The high-speed chase resumed. Once police got the vehicle stopped by pinning the S.U.V. against a utility pole, the driver ran.  Cops caught up with him, and used a stun gun to subdue the man and take him into custody.
