Arrest comes after a third night of protests, including a precinct attack and reporter’s on-air arrest.

The Minneapolis police officer shown in bystander video kneeling on the neck of George Floyd, an unarmed black man who subsequently died, has been charged with murder, officials in Minnesota said on Friday.

Mike Freeman of the Hennepin County Attorney’s Office announced the third-degree murder and manslaughter charges after Derek Chauvin’s arrest was initially announced by the Minnesota Department of Public Safety.

“We have now been able to put together the evidence that we need,” said Freeman.

Police body camera footage, witness statements and a preliminary medical examination of Floyd were among the evidence prosecutors have gathered, he said.

Third-degree murder carries a sentence of up to 25 years in prison. It is defined in the state’s criminal statute as applicable to “whoever, without intent to effect the death of any person, causes the death of another by perpetrating an act eminently dangerous to others and evincing a depraved mind, without regard for human life.”

Chauvin’s arrest came after a third night of arson, looting and vandalism gripped the city as protesters vented rage over Floyd’s death.

Freeman said his office had moved with speed that was not typical for most cases involving police officers, citing the case of Mohamed Noor, who was charged months after the shooting death of an unarmed woman.

“I’m not insensitive to what’s happened in the streets,” said Freeman.

Three other responding officers were fired by the Minneapolis Police Department along with Chauvin the day after the death of Floyd on May 26. They are not currently in custody.

The U.S. Justice Department has also launched an investigation into Floyd’s death. Attorney General William Barr said in a statement on Friday that the Justice Department will “separately decide whether any federal civil rights laws were violated.”
