- Former police officer Derek Chauvin faces another day in court over the deadly arrest of George Floyd.
- A professional MMA fighter who witnessed the arrest is expected back in the stand for a second day of testimony.
- He told jurors he believed that Chauvin was using his knee in a "blood choke" on Floyd's neck during his arrest.
MINNEAPOLIS – A professional mixed martial arts fighter, who witnessed the deadly arrest of George Floyd in Minneapolis last May, is due to return to the stand on Tuesday for the second day of testimony in the murder trial of former police officer Derek Chauvin.
Donald Williams can be heard on a bystander's cellphone screaming at Chauvin, who kept his knee on Floyd's neck for about nine minutes during the arrest on 25 May 2020, shortly after Floyd was accused of passing a fake $20 bill.
Williams calls Chauvin a "bum" in the video, accuses the white police officer of "enjoying" his restraining of Floyd, a 46-year-old handcuffed black man, and told jurors on Monday he believed that Chauvin was using his knee in a "blood choke" on Floyd, a wrestling move to knock an opponent unconscious.
The video, which prosecutors say shows excessive force, sparked outrage and daily demonstrations in the United States and around the world protesting police brutality against black people. The trial is being watched as a litmus test for the US justice system.
'Excessive and unreasonable force'
Chauvin's lawyers are expected to counter that Williams has no knowledge of police manoeuvres.
Chauvin, 45, has pleaded not guilty to second-degree murder, which carries up to 40 years in prison, as well as third-degree murder and second-degree manslaughter. He and the three other officers on the scene were fired the day after Floyd's death.
In opening arguments on Monday, a prosecutor said Chauvin betrayed his badge "when he used excessive and unreasonable force upon the body of George Floyd".
Chauvin's lawyers argued he was simply following training from his 19 years on the force and that the main cause of Floyd's death, which the county examiner ruled a homicide caused by police restraints, was a drug overdose.
