US authorities have charged five former police officers with murder over the death of Tyre Nichols. The 29-year-old was stopped on January 7 for what the Memphis Police Department said was reckless driving. The former officers, who are also Black, are accused of having brutally beaten Nichols after the traffic stop. Nichols died 3 days later in hospital. The officers had been fired after an internal investigation found them to have deployed excessive use of force and to have failed to render aid, police said.
