July 18 (UPI) -- Workers at a Colorado office arrived to find their glass door shattered and reviewed security camera footage to identify the vandal -- an aggressive goat.
A video posted to Facebook by Argonics Inc. shows the security camera footage recorded Sunday afternoon, when a goat approached the glass doors of the Louisville office.
The video shows the goat, which is accompanied by several other goats that watch the action, headbutt one of the doors repeatedly until the glass falls out and shatters.
The goat initially flees, but returns seconds later to repeat the process with the second door.
"Our employees arrived at work on Monday, July 17 to find the doors smashed but nothing taken, and security camera footage showed some surprising vandals," the Facebook post said.
Greg Cappeart of Argonics Inc. said he called police when he arrived for work Monday because he initially suspected human vandals were to blame for the damage.
