Minnesota Department of Public Safety Commissioner John Harrington announced the arresting officer in the George Floyd case has been taken into custody.
Former officer Derek Chauvin has been taken into custody by the Minnesota Bureau of Criminal Apprehension.
Floyd was pronounced dead Monday night after he was taken into custody by police in south Minneapolis. A video that was circulated online shows an officer holding his knee on the back of Floyd's neck for several minutes.
A source with knowledge of the investigation identified the officer as Derek Chauvin. Chauvin and three other officers have been fired in connection to the incident.
Minneapolis Mayor Jacob Frey called on Hennepin County Attorney Mike Freeman Wednesday to file charges.
"I've wrestled with, more than anything else over the last 36 hours, one fundamental question: Why is the man who killed George Floyd not in jail," Frey said to the press Wednesday. "If you had done it, or I had done it, we would be behind bars right now."
Freeman announced Friday he is expected to make an announcement on the case at 1 p.m. Harrington said a charging decision has not yet been made, as it's under Hennepin County's jurisdiction.
