Bodycam footage shows the white police officer claiming he had tasered Mr Nichols and declaring: “I hope they stomp his ass.”
A sixth police officer has been sacked for his involvement in the death of Tyre Nichols, who was beaten by police last month.
Mr Nichols was left in a critical condition after several officers punched, kicked and hit him with a baton in Memphis, Tennessee, after he was pulled over on suspicion of reckless driving on 7 January.
