Police: Original bomb threat at hospital unsolved police say

FARGO - The Moorhead, Minn., man accused of calling in two bomb threats Friday afternoon to Sanford Medical Center in Fargo is not being charged with making a midmorning call that led to a lockdown of the facility.
Fargo police Lt. Joel Vettel said Wednesday that no one was in custody in connection with the midmorning bomb threat call.
Peter Jonathan Rovang, 53, appeared Wednesday in Cass County District Court on felony terrorizing charges related to two other bomb threat calls that came after the hospital was placed on lockdown.
Vettel said police consider Rovang a person of interest in the open bomb threat investigation, although he said there are some differences between the first bomb threat call.
Court documents say Rovang called the hospital twice Friday in connection with a fight he had two days prior with Sanford security guards.
His next court appearance is set for Aug. 20.
