CLAYTON, Mo. (AP) -- A St. Louis County police officer is on paid leave as the department investigates why he was carrying a shotgun during a traffic stop involving Ferguson protesters.
The St. Louis Post-Dispatch reports that an online video shows the officer carrying the gun during a stop Monday night without pointing it at anyone.
A man is heard saying: "Why is he carrying a gun?" Another police officer in a different uniform responds, "I don't know. He's a county officer."
The video's narrator identified the officer by his last name, but St. Louis County police would not confirm it.
A police spokesman said the car was pulled over because the driver failed to use a turn signal. Police said a stolen .38-caliber gun was found in the driver's trunk.
