Just before Midnight on Wednesday a Sioux City Police Officer attempted to stop a vehicle near 27th and Jennings.
The vehicle fled from the officer and proceeded to throw a firearm out of the window.
The vehicle was later located unoccupied near the 2600 block of Douglas St., where officers were flagged down by a man who indicated he was robbed, and kidnapped by gunpoint from his home and forced into the vehicle.
When officers attempted to stop the vehicle he was able to escape from the suspects.
The armed robbery took place near the 2700 block of Virginia.
During the robbery, two individuals received injuries, one of which required medical attention at a local hospital where the victim was treated and released with non-life threatening injuries.
The names of those involved are not being released at this time, and the Sioux City Police Department is investigating.
Anyone with information is encouraged to call the Sioux City Police Department at 258-TIPS, and callers can remain anonymous.
