Protesters calling for the firing of Wauwatosa Police Officer Joseph Mensah engaged police in a 90-minute standoff over the weekend.
The marchers were angered when police arrested two people – one was pulled from his bicycle and tackled.
Wauwatosa police say protesters tried to stop one arrest by fighting officers and blocking the street, keeping squad cars from leaving.
Police say the suspect was arrested for several incidents over the past few days and he will likely face charges.
Despite the Friday incident, the city decided to remove its limited hours for protesting after getting some pushback.
