Cherokee County investigators make arrests as part of a week-long operation. Multiple agencies worked together last week on Operation Vigilant Star. The purpose of the operation was to conduct verification checks on registered sex offenders that reside in Cherokee County to ensure their compliance with the Sex Offender Notification Act. The agencies joined forces to perform 104 compliance checks on 72 state or federal offenders. All but 6 of those offenders were found to be in compliance with the law. Warrants were issued for those 6 and thus far 4 have been arrested for the SORNA violations. At least 2 sex offenders will likely face federal firearms related charges. Investigators also arrested 7 people for drug crimes last week as part of the operation.
