The Riverside Police Department in Califronia is investigating whether employees wrote wrote sexist and racist comments on a local blog.

According to the Daily Breeze, people claiming to be officers left the comments on the blog of Mary Shelton, a reporter for the local weekly The Black Voice News.

The comments were posted between September and mid-December. A message from “Kevin, R.P.D.” referred to “worthless parole animals” in a predominantly Latino and black area of the city. It said: “How about we leave the East Side to who should really patrolling it … Animal Control.”

One post claimed that the department helped “certain females through training” and they take “safe little report calls” rather than arrest parolees or gang members.
