Chauvin trial: police chief says use of force violated policy – video

Derek Chauvin broke Minneapolis police department rules and its ethics code in his deadly arrest of George Floyd last May, the city's police chief testified at Chauvin's murder trial on Monday.

'To continue to apply that level of force to a person proned out, handcuffed behind their back – that in no way, shape or form is anything that is by policy … It’s not part of our training and it’s certainly not part of our ethics or values,' Minneapolis police chief Medaria Arradondo told the jury.

Chauvin has pleaded not guilty to murder and manslaughter charges. Prosecutors have called Arradondo and other police officers to undermine Chauvin's defence that he did only what he was trained to do in his 19 years as a police officer
