A 31-year-old man was behind bars after an incident in which an off-duty police officer was the victim of an aggravated assault Sunday evening in west Topeka, authorities said.

The incident was reported around 5:15 p.m. in the parking lot of 1401 S.W. Wanamaker, which is the address for the Sam's Club store.

Police Lt. Ron Ekis said a man pointed a gun at an off-duty police officer in what he described as a "random encounter." Ekis said the off-duty officer and the suspect didn't know each other. No shots were fired during the incident.

Police Lt. Aaron Jones said the off-duty officer, who was the victim of the aggravated assault, was able to call in the location, description and direction of travel of the suspect who had fled from the scene.

A vehicle matching a description of the one used by the suspect was found by the Kansas Highway Patrol a short time later as it was headed east on Interstate 70 near S.W. Gage Boulevard.

Officers from the Topeka Police Department, Shawnee County Sheriff's Office and Capitol Police responded and assisted with a "high-risk" stop between S.W. MacVicar and S.W. 1st on I-70, Jones said.

The various units shut down I-70 temporarily to ensure the safety of other motorists.

Jones said the driver of the car, Randal S. Hogue, 31, was taken into custody. A stolen handgun and an illegally altered shotgun were discovered in his vehicle.

Hogue was taken to the Law Enforcement Center to be interviewed. While there, he attempted to escape from custody.

Hogue then was taken to the Shawnee County Jail, where he was being held in connection with two counts of aggravated assault, aggravated escape from custody, obstruction, criminal use of a weapon, theft of a firearm and driving while suspended.

Shawnee County District Judge Mary Mattivi on Monday set a $25,000 bond for Hogue during his first appearance and appointed an attorney for him.

No injuries were reported in the incident.
