Angry goats: Animal caught on CCTV shattering glass doors of Denver office (VIDEO)

A herd of destructive goats remain on the loose after the leader smashed the double glass doors of a Denver business.

The bizarre break-in happened Monday at Kryptan Systems, Louisville and much to the amusement of all involved, it was caught on surveillance camera.

Employees of the company arrived at the office Monday morning to find shattered glass everywhere. Assuming it was an act of vandalism they checked out their CCTV footage which revealed some unexpected perpetrators.

The video shows a goat charging at one glass door before knocking it in and fleeing the scene. Members of his goat crew can be seen in the background running past the building.

The billy goat later returns – this time targeting the second door.

"For 20 minutes he just sat and banged on that one side until he broke it, and then he left and came back and decided to break the other side too. I don't know why," employee Greg Cappert told Fox News.

Cappert suggested to Denver CBS that the goat may have been angered after spotting his reflection in the glass.

Louisville Police Department confirmed the goats are still on the run and say they are on the lookout for a “very hairy” horned and possibly hooved suspect.
