Derek Chauvin violated Minneapolis Police Department rules and its ethics code on respecting the "sanctity of life" during the deadly arrest of George Floyd last May, the city's police chief testified at the former officer's murder trial on Monday.

Over 3-1/2 hours of testimony, Chief Medaria Arradondo disputed the defense's claim that Chauvin, who has pleaded not guilty to murder and manslaughter charges, was following the training he had received in his 19 years on the force.

Global's Jackson Proskow has more from the police chief's testimony.
