Here are the details according to Captain Daniel Hahn:
The suspects call the elderly victim and pose as a relative to the victim – They say, “this is your grandson” (or something like that). The victim will respond by saying the name of their relative and the suspect will then play like they are that relative. They say they have been arrested and the victim should wire them money for their bail. The victim will never see this money again because it is a scam. Always be sure who money is being sent to before wiring someone money.
Be sure to spread the word about this scam.
