Hundreds took to the streets of south Minneapolis Tuesday night to protest the death of George Floyd while in police custody.

Demonstrators carried signs that read “I can’t breathe,” “Black Lives Matter” and “KKKops” as they marched to the Minneapolis P-D’s Third Precinct. Protesters were mostly peaceful before a police vehicle was spray painted, a squad car had a window broken and rocks were thrown at a building. Police deployed chemical irritants at them at the Third Precinct. Video of a Minneapolis police officer kneeling on George Floyd’s neck until he appears to lose consciousness went viral Monday night. He died after arriving at the hospital. Police say Floyd was a suspect in a forgery case and resisted arrest. All four officers involved in the incident have been fired.
