On Saturday, the mayor said that the new killing has injected fresh anger into demonstrations against racism and police brutality after an officer shot a black man fatally during an arrest in the US city of Atlanta.
Local media reported that protesters blocked the interstate highway and light up Wendy's, which killed Rayshard Brooks, 27, late Saturday.
Brooks fell asleep in his car while in the drive-through lane at Wendy's fast food restaurant late Friday, and the employees called up the police to file a complaint of him blocking the way for other customers, an official report said.
The Georgia Bureau of Investigation said that he failed a check of sobriety and resisted while the police were attempting to arrest him.
The report continued, Surveillance video showed "that during a physical struggle with officers, Brooks obtained one of the officer's Tasers and began to flee from the scene."
The report stated, "Officers pursued Brooks on foot and during the chase, Brooks turned and pointed the Taser at the officer. The officer fired his weapon, striking Brooks."
Brooks was taken to a hospital but died after the operation, the report added, he injured a police officer.
Disarray occurs in the face of systemic institutional racism, with mass civil disarray caused by the murder of another African American man, George Floyd, on May 25, while under police custody.
Floyd died almost nine minutes after a white Minneapolis policeman knelt on his neck.
In the weeks afterwards, protests that spread throughout the country and around the world have forced talks on legacy slavery, colonialism and violence against people, and on the militarization of the US police.
For more than two decades Shields had been working at the Atlanta Police Department.
The mayor said, "Because of her desire that Atlanta is a model of what meaningful reform should look like across this country, Chief Shields has offered to immediately step aside as police chief."
