Derek Chauvin, the former Minneapolis Police officer found guilty on all counts for the murder of George Floyd, allegedly kneeled on a Black teen in 2017. 

After being convicted for Floyd’s murder, the Department of Justice is now considering whether or not to charge him for his excessive use of force in the incident that took place five years ago.

As state prosecutors began preparing for Chauvin’s trial, they received several videos of Chauvin’s behavior in the past, ABC News reported. 

The videos from the 2017 incident allegedly show Chauvin striking a Black teenager in the head with a flashlight before holding him down with his knee for nearly 17 minutes while ignoring his cries for help. 

The teen, who has not been named, lost consciousness while Chauvin kneeled on his neck, Minnesota State Prosecutor Matthew Frank said. 

Months ago, federal prosecutors brought people who witnessed the 2017 incident before a federal grand jury and they are still investigating. 

State prosecutors wanted to use the video in the trial to show jurors a pattern of Chauvin’s behavior, but Judge Peter Cahill would not allow it. 

Officials with the Minneapolis Police Department were briefed on the DOJ’s interest in the incident. 

“We will assist the DOJ with anything that they need, and the chief has pledged full cooperation with any investigating agency,” Minneapolis Police Department spokesman John Elder said.

On Tuesday, a jury found Chauvin guilty of second-degree murder, third-degree murder and second-degree manslaughter after just 10 hours of jury deliberation. 

The next day, Attorney General Merrick Garland announced that the Department of Justice is launching a probe into the Minneapolis Police Department’s policies.
