The Kent County Sheriff's office says an old scam is back. They've issued and advisory about a phone scam involving police impersonators and the sex offender registry.

According to a release, two residents have received calls from someone pretending to be a Kent County Sheriff Deputy. The caller told residents that their family member, who is a sex offender, is in violation of the Sex Offender Registry and will be arrested unless a fine is paid.

The calls were made to senior citizens who do have a family member on the Sex Offender Registry.

The residents were told to call a phone number to "resolve the matter". Upon calling, someone answered the phone by saying  "Kent County Sheriff's Department."

The Kent County Sheriff's Office says they do not solicit funds in this way and that law enforcement in general will never ask for payment in the form of a voucher, gift card, iTunes gift card, or prepaid credit card.

If you get a call like this, call your local police non-emergency number to report it. In Kent County that number is 616-632-6100.
