Employees at a Casper business were threatened by an irate customer.

Thirty-seven year old Robbey Swank is facing one charge of making terroristic threats, in which he's accused of threatening employees at the Verizon store at Eastridge mall friday morning, August 17th.

A mall security guard told police a Verizon manager claimed Swank  had been screaming and threatening employees at the store and said if he had a gun, he'd use it.

Police later found Swank at his home, where he told officers he was upset that Verizon had taken half of his deposit and applied it to a late payment.

Officers found a handgun and three rifles during a search of his home.

Swank is being held on twenty-five thousand dollars bond, and could receive up to three years in prison if convicted.
