All indictments must be presented to the court by the foreman of the grand jury in the presence of at least 11 other jurors, must be endorsed "filed" and must have the endorsement dated and signed by the clerk; but no entry of an indictment found must be made on the minutes, nor must any indictment be inspected by any other person than the district attorney, the presiding judge and the clerk of the court until the defendant has been arrested or has given bail for his appearance.
