ATLANTA -- Officials in Georgia say they are investigating an online threat against people protesting the killing of Ahmaud Arbery, a black man who authorities say died at the hands of two white men as he ran through a neighbourhood.
The Georgia Bureau of Investigation on Sunday said that it 鈥渉as been made aware of a Facebook post that contains a threat to future protests related to Ahmaud Arbery. We are actively investigating this situation and will provide pertinent updates as necessary.鈥
Spokesperson Nelly Miles declined to provide further information.
Several hundred people protested the case Friday in Brunswick, near the site where Arbery was fatally shot on Feb. 23. National outrage over the case swelled last week after video surfaced that appeared to show the shooting. The social justice arm of Jay-Z's Roc Nation entertainment company on Sunday called on Georgia officials to take quick action in the case.
Shortly after the video's leak, Gregory McMichael, 64, and his son Travis McMichael, 34, were arrested and charged with murder and aggravated assault. The arrests came hours after officials asked the GBI to start investigating. The inquiry was previously in the hands of local officials.
The father and son said they thought Arbery matched the appearance of a burglary suspect who they said had been recorded on a surveillance camera some time before.
Arbery's mother, Wanda Cooper Jones, has said she thinks her 25-year-old son, a former high school football player, was just jogging in the neighbourhood before he was killed.
On Saturday, the GBI confirmed that it has obtained other photos of video that might shed light on the case. The Atlanta Journal-Constitution published footage from a surveillance camera at a Brunswick home near where Arbery was shot that shows someone who appears to be Arbery walking into a home under construction. Arbery then came back out and ran down the street. Someone else comes out across the street from the construction site, and then a vehicle drives off farther down the street, near where Travis McMichael lives.
Lawyers for Arbery's family say the video bolsters their position that Arbery did nothing wrong, and shows he did not commit a felony. Under Georgia law, someone who isn't a sworn police officer can arrest and detain another person only if a felony is committed in the presence of the arresting citizen.
鈥淎hmaud's actions at this empty home under construction were in no way a felony under Georgia law,鈥 the lawyers wrote in a social media post. 鈥淭his video confirms that Mr. Arbery's murder was not justified and the actions of the men who pursued him and ambushed him were unjustified.鈥
