In the event a petitioner who has been convicted of a Class X felony is granted a release, after the Governor has communicated such decision to the Board, the Board shall give written notice to the Sheriff of the county from which the offender was sentenced if such sheriff has requested that such notice be given on a continuing basis. In cases where arrest of the offender or the commission of the offense took place in any municipality with a population of more than 10,000 persons, the Board shall also give written notice to the proper law enforcement agency for said municipality which has requested notice on a continuing basis.
