The Savages have repeatedly accused Kelly of brainwashing their daughter, who has denied allegations of abuse.
Mason surrendered in January, several months after a warrant was issued for his arrest. He was later released on $10,000 bond.
Gerald Griggs, an attorney for the Savage family, released an emailed statement following Mason’s indictment.
“Today's indictment of Henry James Mason, the former manager of Robert Kelly, further underscores the public accountability that victims and families are pressing on Mr. Kelly and his team,” Griggs said.
“The Savage family will not be bullied or threatened in their quest to reunite with Joycelyn. Let this be a message to all associates of Robert Sylvester Kelly that the Savages are serious about justice and accountability,” he said.
Kelly pleaded not guilty to 11 additional sex-related charges Thursday, including four counts that carry a maximum prison term of 30 years in prison, according to The Associated Press.
Kelly had denied the allegations.
His next court date is scheduled for June 26.
