Rule 605. Mistrial.

 (A)  Motions to withdraw a juror are abolished.

 (B)  When an event prejudicial to the defendant occurs during trial only the defendant may move for a mistrial; the motion shall be made when the event is disclosed. Otherwise, the trial judge may declare a mistrial only for reasons of manifest necessity.

   This rule replaces the practice of moving for the withdrawal of a juror.
