The incident occurred when the police were confronting protesters outside the police department.

 "A police source said one of the officers is a St. Louis County officer and the other a Webster Groves officer. The source said both officers are expected to survive. The officers were taken to Barnes-Jewish Hospital, where there was a large number of police vehicles," St. Louis Post-Dispatch reported.

"The protesters seemed to be two camps. The first were there to make a point that they weren't satisfied with the resignations of City Manager John Shaw and Police Chief Thomas Jackson. They were chanting in unison. The other one was volatile, angry, hurling profanities at the police, media and other protesters. Some skirmishes broke out among the factions," the newspaper reported.
