A 43-year-old Lawrence man was arrested Friday afternoon after threatening an employee of Westridge Wash & Lube, 3530 West Sixth St.

According to Lawrence police Sgt. Dave Hubbel, a man had been arguing with the attendant about the functionality of the facility’s vacuum. The man was upset and tapped what appeared to be a handgun on the window in front of the attendant. The man then left the scene but the attendant was able to record the license plate of the vehicle.

Officers later found the suspect in his home and arrested him on charges of aggravated assault. A BB gun was found in the vehicle.

No one was injured during the incident.
