No statement, or any information procured therefrom, with respect to the specific offense with which the defendant is charged, which is made to any probation officer subsequent to the granting of diversion, shall be admissible in any action or proceeding.
In the event that diversion is either denied, or is subsequently revoked once it has been granted, neither the probation investigation nor statements or information divulged during that investigation shall be used in any pretrial sentencing procedures.
