Derek Chauvin, the cop who was caught on camera using his knee to pin George Floyd’s neck to the ground has been arrested in the deadly incident, according to reports Friday.

Derek Chauvin was taken into custody by state authorities, Minnesota Public Safety Commissioner John Harrington said, according to tweets from multiple reporters.

It’s unclear what charge or charges will be filed, but Harrington had described Floyd’s death as a “murder” during a news conference earlier in the day.

He told reporters about the arrest after getting a phone call from the superintendent of the Bureau of Criminal Apprehension, according to a tweet from a KMSP-TV/FOX 9 reporter.

Chauvin, who is white, was fired following the release of a cellphone video that showed him ignoring bystanders’ pleas to release Floyd, who was black and was heard saying “I can’t breathe” before apparently losing consciousness.

Floyd’s death sparked three nights of increasingly violent protests in Minneapolis and led to the burning of a police station Thursday night.

Activists and others have demanded the prosecution of Chauvin as well as three other cops who were at the scene of Floyd’s arrest Monday for allegedly using a counterfeit $20 bill to try to buy groceries at a deli.

The three other cops were also fired.
