Ohio police officials released officer body-camera footage of a 25-year-old Black man killed in a hail of bullets fired by eight officers while he was unarmed and running away.

As Jayland Walker's family has demanded answers about the circumstances of last week's killing, which authorities said occurred following a police chase, large protests have erupted in Akron, Ohio, with demonstrators marching on the city's police headquarters.

Akron Mayor Dan Horrigan and Police Chief Steve Mylett, during a news conference Sunday afternoon, joined the Walker family in calling for peaceful protests and for patience as the investigation continues in the man's death.

"When an officer makes the most critical decision in his or her life as a police officer, it doesn't matter where in the country this happens, when they make that most critical decision to point their firearm at another human being and pull the trigger, they've got to be ready to explain why they did what they did," Mylett said Sunday. "They need to be able to articulate what specific threats they were facing, and that goes for every round that goes down the barrel of their gun."
