MINNEAPOLIS — The police officer seen on video kneeling on the neck of George Floyd, a handcuffed black man who died in custody after pleading that he could not breathe, was arrested Friday after three days of often-violent protests that resulted in fires and looting across parts of Minneapolis.

News of the arrest came moments after Minnesota Gov. Tim Walz acknowledged the “abject failure” of the response to this week’s protests and called for swift justice for officers involved.

Walz said the state would take over the response to the protests and that it’s time to show respect and dignity to those who are suffering.

The governor cited a call he received from a state senator who described her district “on fire, no police, no firefighters, no social control, constituents locked in houses wondering what they were going to do.

His comments came the morning after protesters torched a police station that officers abandoned during a third night of violence.
