Police in Cookeville are warning citizens about a scam in which a caller pretends to be a grandchild in need of money.
According to a report in The Cookeville Herald-Citizen, one such attempt was tried unsuccessfully recently in Putnam County.
Officers said a 90-year-old man received a call from someone claiming he was the man's grandson, was in jail in British Columbia and needed $2,400 to be released.
The man hung up, checked the Internet and found reports of similar scams.
Police advise the public to be skeptical of such calls.
They suggest hanging up the phone and then contacting other family members who know the whereabouts of the relative.
