The Carmel Police Department is cautioning residents to the so-called Grandparent scam making it's way around the area once again.  This phone scam involves criminals calling someone, claiming to be a relative who needs help being released from custudy due to an arrest, accident or other ruse.  Carmel Police say the actual police will not demand money over the phone, especially not in the form of gift cards.  Anyone receiving this type of call is urged to not give out any personal identifying information and to hang up.  The call should also be reported to Carmel Police.
