Appellant has offered no objection to this motion, nor additional argument. Therefore, this court having granted the motion to withdraw, we now affirm the conviction (see Snell v. State, 246 Ga. 648 ( 272 S.E.2d 348); Avery v. State, 161 Ga. App. 229 ( 288 S.E.2d 298)). We are satisfied that the evidence adduced at trial, though circumstantial, was sufficient to enable any rational trier of fact to find that Williams in several particulars violated the terms of his probation beyond reasonable doubt.
