"During the initial investigation, police established the threat was not a legitimate one," Hunter said.
"Police have since been investigating the culprit allegedly responsible for the threat."
Hunter said police took such threats very seriously.
"These types of false threats take up a significant amount of police and other emergency services resources and cause widespread disruption for members of the public, who are just trying to go about their day-to-day business.
"We want to send a message that anyone who makes false threats can expect to be prosecuted and held to account."
As the matter is now before the Court, police were not in a position to comment further, Hunter said.
