A St. Louis-area police department announced on Thursday it had fired on officer who posted offensive comments online about people protesting the fatal police shooting of unarmed black teenager Michael Brown.

CNN reported that Glendale, Mo. Police Officer Matthew Pappert was fired after posting comments to Facebook that likened the Ferguson, Mo. protestors to “rabid dogs” that should be “put down.”

The Glendale Police Department was notified of the comments and initially suspended Pappert on August 22. He issued an apology via a written statement because, as his lawyer put it, according to CNN, “He’s a mess right now. It’s an embarrassment.”

Pappert’s comments are part of a slew of incidents that have occurred in the midst of the Ferguson protests involving police officers making inappropriate comments. Officers such as Kansas City officer Marc Catron, who was being investigated for his Facebook post of a man he mistook for Michael Brown, and Lt. Ray Albers, who was forced to resign from the St. Ann, Mo. police department after he told protestors he would “fucking kill” them.
