In re Kevin F.

After determining that defendant Kevin F. (Minor) committed robbery, the juvenile court declared Minor a ward of the court and placed him on probation with conditions. On appeal, Minor contends (1) there is insufficient evidence he committed robbery, and (2) the court’s probation condition prohibiting him from possessing weapons is unconstitutionally vague and overbroad. In the unpublished portion of this opinion, we reject Minor’s challenge to the sufficiency of the evidence. In the published portion of this opinion, we hold the challenged probation condition must be modified. We will affirm the judgment as modified.
