IRON MOUNTAIN — A 40-year woman was in court Tuesday after being accused of making bomb and shooting threats at First National Bank & Trust late Monday morning.

Heather Dabb was arraigned in Dickinson County 95B District Court on the charge of false report of threat of terrorism, according to a news release from Jeffery Solka, director of police and fire services for the Iron Mountain Police Department.

Dabb’s bond was set at $50,000. The offense is a felony that carries a maximum penalty of 20 years in prison and/or a fine of up to $20,000.

“The false report of threat of terrorism charge pertains to individuals who either threaten to commit an act of terrorism or knowingly make a false report about such an act to another person,” Solka said in the news release. “This is a criminal offense that is taken very seriously, especially given the potential harm and disruption that can result in these claims.”

The bank at 223 S. Stephenson Ave. in downtown Iron Mountain reported the threats at about 10 a.m. Monday. The building was evacuated and lockdown protocols activated at FNB locations that included the Kingsford and South branch offices.

First National Bank & Trust also closed all Dickinson County sites for the day.

The Iron Mountain Police Department was assisted by the Kingsford Public Safety Department, Dickinson County Sheriff’s Department and Dispatch Center, Michigan State Police and the FBI field office in Marquette.

The IMPD is continuing its follow-up investigation.
