In the moments before the fatal confrontation, the McMichaels, who are white, armed themselves with a pistol and shotgun and pursued Mr Arbery in a pickup truck in the Satilla Shores neighbourhood.
The delay in criminal charges and a mobile phone video of the shooting leaked shortly before the May 7 arrests fuelled national outrage over Arbery's death, with many saying he was targeted because he was black. There was no immediate information on bond for Mr Bryan. During the encounter, Travis McMichael shot and killed Arbery, prosecutors said.
ABC News has reached out to Bryan's attorney, Kevin Gough, for comment.
The footage has sparked outrage from civil rights activists, who see it as the latest incident of US law enforcement allowing white perpertrators to go unpunished in the unjustified killing of a black man. It's the only mention in the police report of any potential involvement by Bryan.
"We called for his arrest from the very beginning of this process", attorneys S. Lee Merritt, Benjamin Crump and L. Chris Stewart said in a statement.
On Monday, Gough also said that Bryan was unarmed at the time of the shooting and "was not in communication with Gregory or Travis McMichael, or anyone else, during that timeframe".
The clip appears to show Mr Arbery running down a tree-lined street as the McMichaels wait ahead for him in their vehicle.
"The evidence says that he went from his home, according to his attorney, and minutes later he was in his truck following Ahmaud Arbery, who was a jogger in his neighborhood, around", Merritt told CNN.
Gregory McMichael worked as an investigator for the local district attorney for more than two decades before he retired previous year. Attorneys for the father and son have urged people not to rush to judgment in the case.
