A jury has been selected in the federal trial of three former Memphis police officers charged with federal civil rights violations in the beating death of Tyre Nichols.

No criminal charges will be brought against a Memphis police officer who was fired for his involvement in the traffic stop that led to the death of Tyre Nichols, the Shelby County District Attorney said Tuesday.

A prosecutor says a former Memphis police officer who hit Tyre Nichols with a stun gun during a traffic stop that preceded Nichols’ brutal beating by other officers won’t be charged criminally.

One of three Memphis Police officers who initially detained Tyre Nichols last month approached Nichols’ car while brandishing his gun.

Officials say a sixth Memphis officer was fired Friday after an internal police investigation showed he violated multiple department policies in the violent arrest of Tyre Nichols, including rules surrounding the deployment of a stun gun.

A sixth Memphis police officer has been relieved of duty after the traffic stop that led to Tyre Nichols’ death earlier this month, police said Monday.
