The Polk County Sheriff’s Office is investigating a carjacking that happened Wednesday.
Just after 3:00 p.m., deputies received calls of a suspicious male in the road trying to flag down cars in the 9500 block of Northwest Beaver Drive.
While deputies were on their way to respond, a second call came in that the suspect stopped a van, assaulted the driver and stole the van. Deputies looked for the suspect but could not find him.
The van was later captured speeding by the Polk County mobile speed camera a short distance away.
About five hours later the van was found in Des Moines. No one was inside. The van is being processed for evidence.
The victim was not injured during the assault.
