Derek Chauvin, a former Minneapolis police officer who was filmed kneeling on George Floyd's neck before he died on Monday, has been arrested, local authorities said.

Chauvin was among the four officers involved in Floyd's violent arrest that has since spurred days of protests in Minnesota's largest city. Chauvin is white and Floyd was black.

Floyd died after being arrested on the suspicion that he attempted to use a counterfeit bill. His arrest, which was caught on tape by onlookers, shows Chauvin kneeling on Floyd's neck for more than seven minutes as Floyd cries out that he cannot breathe.

It was not immediately clear whether Chauvin had been charged with a crime. Hennepin County Attorney Mike Freeman was scheduled to deliver news of a "major development" related to Floyd's death later Friday afternoon.

Floyd's death has prompted calls from local and national figures for Chauvin's prosecution, and a federal investigation led by the Department of Justice and the Federal Bureau of Investigation.

"The Department of Justice has made the investigation a top priority and has assigned experienced prosecutors and FBI criminal investigators to the matter," the agencies said in a joint statement Thursday.

President Donald Trump, who has in the past told officers not to worry about injuring those they arrest, has shown sympathy for Floyd's case.

"Justice will be served," Trump wrote in a post on Twitter on Wednesday.

Joe Biden, the apparent Democratic presidential nominee, has also weighed in. During a livestream on Friday afternoon, Biden thanked Floyd's family for speaking with him, and pledged: "I promise you, we'll do everything in our power to see that justice is had."
