MEMPHIS, Tenn. (AP) — Five Memphis Police Department officers have been fired for excessive use of force, failure to intervene and failure to render aid — stemming from an arrest during a traffic stop of a man who later died in a hospital, officials said Friday.

The police chief said Tadarrius Bean, Demetrius Haley, Emmitt Martin III, Desmond Mills, Jr. and Justin Smith were involved in the Jan. 7 arrest of Tyre Nichols, 29, who was Black. The Memphis Police Department conducted an internal investigation into the arrest of Nichols, who died three days later, and the discipline came after the probe’s conclusion, authorities said.

The five officers who were fired are all Black, according to the Memphis Police public information officer.

The U.S. Justice Department has opened a civil rights investigation, and the Tennessee Bureau of Investigation also is looking into the force used in the arrest.

Nichols’ family, along with protesters who have rallied at a police station and the National Civil Rights Museum, have pushed for the release of police body camera footage and have called for officers to be charged.

Relatives have accused police of beating Nichols and causing him to have a heart attack. Authorities have said that Nichols experienced a medical emergency.

Nichols was arrested after officers stopped him for reckless driving, police said. There was a confrontation when officers approached the driver, and he ran before he was confronted again by the pursuing officers, who arrested him, authorities said. He complained of shortness of breath and was hospitalized. Officials said a cause of death has not yet been determined.

Relatives have said that the officers who pulled over Nichols were in an unmarked vehicle — and that he experienced cardiac arrest and kidney failure from the officers beating him.

Memphis police chief Cerelyn “CJ” Davis and Mayor Jim Strickland said Tuesday that video footage of the arrest will be released after the police department’s investigation is completed and the family can review it.

The city leaders are arranging a meeting early next week with Nichols’ family, according to a joint statement from both Strickland and Davis.
