An adjudication of delinquency shall not be entered against a juvenile based upon the testimony of an accomplice or a solicited person unless corroborated by other evidence which tends to connect the juvenile with the commission of the offense; and the corroboration is not sufficient if it merely shows the commission of the offense or the circumstances thereof. Corroboration of the testimony of victims shall not be required.
