Arradondo testified for over 3.5 hours, and attempted to refute the claims by defence that Chauvin was merely acting out based on the training he had received in the force. Chauvin has pleaded not guilty to murder and manslaughter charges.

It is highly unusual for a police chief to testify against their former subordinates. Soon after the incident, Chauvin was fired by Arradondo, along with other officers involved in the incident.

Last year, the chief put out a statement calling it murder - "This was murder — it wasn't a lack of training."

"I vehemently disagree that that was appropriate use of force for that situation on May 25," Arradondo testified.

"It's contrary to our training to indefinitely place your knee on a prone, handcuffed individual for an indefinite period of time," he said.
