The Madison County Sheriff's Office is the latest local police agency to report a telephone scam targeting senior citizens.

They say a man is calling seniors indicating he's their grandson, is in some type of trouble and needs money.

In one case, the recipient of the call asked a question that only the grandson could answer and the caller immediately hung up.

Sheriff Allen Riley is reminding residents to never give out personal information over the phone if they're not 100% sure of who they're  talking with.

State Police have recently investigated two similar incidents in Herkimer County.
