Bismarck Police are investigating a call from a man who tried to extort $4,000 from Ramada Limited.

A 31-year-old front desk attendant says the caller claimed he was a dangerous man and he would kill everyone in the hotel if she didn't pay him.
Investigators say the call was traced to a Texas phone number.
The victim says the caller told the girl to stop pacing back and forth.
Officers believe the perpetrator had access to the surveillance cameras.
The case is still under investigation.
