North Omaha officers used flash-bang devices Thursday night after a Westroads Mall shoplifting call turned into a barricade situation near 39th and Fort streets.
Police said the suspect fled a vehicle stop, entered a home, and pointed a gun at an officer after being tracked by helicopter from the mall.
Two people believed to be in the basement were later described by Omaha Police as innocent and able to get out of the house; no injuries or arrests were reported.
Emergency phone alerts told residents near 38th and Camden streets to shelter in place as police, including U.S. Marshals, flooded the area in what remained an active investigation.
