NORTH FORT MYERS, Fla. - The scam began with a call for help.

"Hi grandpa. This is your grandson...," said the victim who asked that we not identify him.

The thief claimed to be the victim's grandson and said he was arrested in Canada for driving drunk. The victim trying to help drove to his bank and withdrew $8,500 from his bank to bail him out.

"I was so happy. I was thrilled that he called 'grandpa'. I'm not a rich guy and I do intend that the little money I do got to spend it on my grand kids," he added.

The victim grew suspicious only after wiring the money. When he called his son in Southern California he learned his grandkid was at a dentist appointment in the U.S.

The victim says his grandson plays hockey and travels to Canada for games. That's why he didn't think twice about where he was arrested.

Western Union does warn customers of these types scams, but it can't stop people from wiring the money.
