In the court today Wilson remained impassive in the dock as abuse was shouted at him.
"You're a f****n dead man walking," one young man said.
A woman screamed about the alleged victim's children and another man was escorted out by security guards as he swore at them not to touch him.
Justice Graham Lang, who was presiding over the hearing via audio visual link, asked for calm and ordered the removal of any of the 20-plus members of the gallery who could not be quiet.
Wilson was remanded in custody until October 4 while the court awaits a Section 38 report under the Criminally Mentally Impaired Persons Act to assess whether he is fit to stand trial.
A tentative trial date was set down for two weeks from November 27 next year.
