A white South Carolina police officer has been charged with murder over the shooting death of a black man who appeared to be fleeing from him.
State investigators arrested North Charleston police officer Michael Slager on Tuesday after viewing a video of the shooting.
Authorities say the victim, Walter Lamer Scott, was shot after the officer already hit him with a stun gun.
The US Department of Justice is set to launch an investigation.
“When you’re wrong, you’re wrong,” North Charleston Mayor Keith Summey said, announcing the arrest. “When you make a bad decision, don’t care if you’re behind the shield or a citizen on the street, you have to live with that decision.”
The incident on Saturday began after Scott’s car was stopped for having a broken rear light, local media reported.
A video of the incident published by the New York Times shows a brief scuffle before Scott begins running away. The video then shows the officer firing several shots at Scott, who falls to the ground.
The shooting occurred as heightened scrutiny is being placed on police officer shootings, particularly those that involve white officers and unarmed black suspects.
A grand jury declined to indict Ferguson, Missouri officer Darren Wilson over the fatal shooting of Michael Brown last August, leading to nationwide protests.
