Sixth Memphis police officer fired for role in arrest of Tyre Nichols

Investigation finds Preston Hemphill violated rules regarding stun gun use, and video shows him saying I hope they stomp his ass'

A sixth Memphis officer was fired on 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, officials said.

Preston Hemphill had previously been suspended as he was investigated for his role in the arrest of Nichols, who died three days later. Five Memphis officers have already been fired and charged with second-degree murder in Nichols's death.
