Tucson police Chief Chris Magnus experienced what all drivers dread — the flashing blue-and-red lights in the rear-view mirror.

In a traffic encounter captured on a police body camera, a Tucson officer pulled over a dark-colored SUV for a red-light infraction only to learn that the driver was his boss.

According to the video the officer tells Magnus that he observed the SUV turn left onto North Alvernon Way from East Broadway after the light had turned red.

It was only after he walked up to the SUV that it appears the officer realized that it was Magnus, who was wearing his uniform.
