Fargo, ND  —  Fargo Police investigated a bomb threat called in to the Radisson Hotel in Downtown Fargo around 6-p.m. Saturday (Sept 15,2012.)

As soon as the call was made directly to the hotel, guests and staff were evacuated from the entire building.

 Police determined that it was not a viable threat, and that there was no risk to the public.

Guests and staff returned to the Radisson and operations were back to normal.

It’s the fourth bomb threat in one week in the valley.

Following threats to  Fargo Hector International Airport on Tuesday, Grand Forks International Airport on Wednesday and North Dakota State University on Friday, Fargo Police  and the FBI are considering each of the bomb threats as separate incidents, as the investigation into possible connections.
