2:10 PM PT -- Mason has issued a statement, saying, "Unfortunately, my accusers and their representatives have been successful at manipulating the media and now the judicial system."

He continues, "My team and I will present facts soon that will discredit any and all accusations that suggest that I have engaged in any acts of bullying, harassment, or aggressive acts against my accusers." He insists that, not only are these accusations false, but he has been "instrumental in attempts to assist my accusers in their quest to re establish a relationship with their adult daughter."

8:40 AM PT -- The judge ordered Mason to stay away from Joycelyn Savage and her family, and have absolutely no contact with them ... according to the Henry County Court Clerk.

He was released on $10k bond and has also been told he can't leave the country unless he gets court approval first.

One of R. Kelly's former managers has surrendered to authorities on charges he made terroristic threats against a family of one of the singer's alleged victims.

As TMZ first reported, Joycelyn Savage's father told us James Mason called him in May 2018, and threatened, "I'm gonna do harm to you and your family, when I see you I'm gonna get you, I'm going to f***ing kill you."

The Henry County Sheriff's Dept. issued an arrest warrant last August for felony terroristic threats and acts and, Friday morning, Mason turned himself in.

He was released on $10,000 bond.

Joycelyn Savage has said she is not being held against her will, but her parents firmly believed their daughter has been brainwashed and they have mounted a full-court press to free her.

The lawyer for the Savage family responded to Mason's surrender, saying, "Let this be a message to R. Kelly's staff that we won't be bullied or threatened. We will continue to pursue legal action against any and all threats to the safety of the Savage Family."

He continued, "Our goal has always been to bring Joycelyn Savage home safely and we will not be deterred."
