MINNEAPOLIS (AP) — Minneapolis’ mayor and police chief have changed a policy that dictates how officers should carry out so-called no-knock warrants, saying officers will be required to announce their presence as they enter premises, as well as make periodic announcements while inside.

Wednesday’s announcement by Mayor Jacob Frey and Police Chief Medaria Arradondo comes six months after the death of George Floyd and is one of several changes the department has implemented amid calls to defund and revamp the police department. The new policy goes into effect Monday.

Floyd, a Black man who was handcuffed, died May 25 after Derek Chauvin, who is white, pressed his knee against Floyd’s neck as Floyd said he couldn’t breathe. Chauvin was charged with second-degree murder and manslaughter, and three other former officers face aiding and abetting charges. Floyd’s death renewed calls for an end to police brutality and racial inequities, sparking protests in Minneapolis and beyond.
