(a) Except in cases where conditional discharge or supervision was imposed for a petty offense as defined in Section 5-1-17, when a petition is filed charging a violation of a condition, the court may:
(1) in the case of probation violations, order the issuance of a notice to the offender to be present by the County Probation Department or such other agency designated by the court to handle probation matters; and in the case of conditional discharge or supervision violations, such notice to the offender shall be issued by the Circuit Court Clerk; and in the case of a violation of a sentence of county impact incarceration, such notice shall be issued by the Sheriff;
(2) order a summons to the offender to be present for hearing; or
(3) order a warrant for the offender's arrest where there is danger of his fleeing the jurisdiction or causing serious harm to others or when the offender fails to answer a summons or notice from the clerk of the court or Sheriff.
Personal service of the petition for violation of probation or the issuance of such warrant, summons or notice shall toll the period of probation, conditional discharge, supervision, or sentence of county impact incarceration until the final determination of the charge, and the term of probation, conditional discharge, supervision, or sentence of county impact incarceration shall not run until the hearing and disposition of the petition for violation.
