The Cass County Sheriff's Office has fielded several complaints.

According to Cass County, an individual claiming to be a member of their department is contacting people on the Sex Offender Registry and telling them they need another sample of DNA or they will go back to prison.  They've also told them that they have active warrants out for their arrest.

There were some instances where the sex offenders were asked for money by the unknown caller. It appears all of these calls were claiming to be from the Cass County Sheriff's Office.

The sheriff's office advises do not meet any individual without verifying who they are. The sheriff's office will never ask you to meet an officer and give him money.

If you receive any calls similar to this you're asked to call and report the incident to Cass County Central Dispatch at 574-722-6060 or contact 574-753-7800 and speak with the Sex Offender Coordinator.
