Cell phone video from a shopper inside The Shoppes at Bel Air shows mall security’s new K9 team working together to put an end to an altercation. Lamont Fagan posted the video publicly to his Facebook page on Monday night. 

In the video, you can see two men walking and gesturing at one another as if they are about to fight. Mall security, including K9 Kosmo, move in quickly. 

The Shoppes at Bel Air added Kosmo, a 3-year-old Dutch Shepherd, and K9 Officer Justin Kestler to the security team last month.
