SHARONVILLE, Ohio (AP) – A suburban Cincinnati grocery checkout employee is being credited with preventing an 86-year-old man from becoming the latest “grandparent scam” victim.

WLWT-TV reports that Russell Fleckenstein recently received a call from a scammer pretending to be his grandson in jail.

The Army veteran from Sharonville says the scammer said he was in trouble and needed $2,000 in bail money. He says he was initially skeptical, but has a hearing aid so he ultimately believed the caller.

Fleckenstein was instructed to go to Kroger and put the money on iTunes gift cards and call back with the card codes.

But he says Kroger employee Cathy Wilkings was immediately aware of the scam and wouldn’t sell him the gift cards.

Fleckenstein says Wilkings helped him call the police.
