ELIZABETHTOWN, Ky. (WDRB) -- Police in Elizabethtown say people are receiving calls from someone who claims to be holding their family members hostage.

It has happened a few times over the past week but at this point, but officers are not yet ready to call it a scam.

"We're calling it a prank call at this point, but we don't know for sure, at this point, if that's all it is," said John Thomas with the Elizabethtown Police Department.

In most scam calls, the caller would ask for money. But with these calls, that hasn't happened.

"Hasn't made any concrete demands, and that's kind of the prank call angle of this," Thomas said. "If they were true scammers, they would probably be demanding a certain amount of money and very specific instructions on how to pay for it."

The one time the caller did, he or she didn't follow through.

"He's made a couple of insinuations that he requires money, but one rather astute potential victim tried to ask him for details about how much money he wants and how he can pay for it, and he eventually hung up without providing any details," Thomas said.

When you call one number that has been used by the caller(s), a full voicemail box message is all you get. 

"We've not been able to verify that its even a genuine phone number," Thoma said. "There are innumerable ways to mask a phone number ... to create a phone number."

Nonetheless, for those who have received the prank calls, it's been anything but funny.

"In a couple of instances, people have not been aware of the whereabouts of the family member they've threatened to have held hostage," Thomas said. "So obviously, it's very frightening."

If you receive one of those phone calls, you're urged to call police as soon as possible.
