DENVER — On a dark, cold morning in Denver, a man in a wheelchair was struggling to maneuver across the snow-covered intersection.

A Denver police officer happened to be driving by and stopped when he saw the man stuck in the crosswalk.

Surveillance cameras were rolling as the officer stopped, turned on his lights, got out of the vehicle and helped the man across the street.

“Security cameras are normally set up to capture nefarious activity, but sometimes they catch someone in an act of kindness,” the Denver Police Department said on Facebook.

The length of the video is about 10 minutes, but the police department said it sped it up “for your viewing convenience.”
