The incident occurred just days after conservative political activist Charlie Kirk was shot dead during an event at Utah Valley University in Orem, Utah, recently.

The suspects have been identified as Adeeb Nasir, 58, and Adil Justice Ahmed Nasir, 31.

They are now facing multiple charges, including Threat of Terrorism, Possessing Weapons of Mass Destruction and Possessing Explosive Devices.

The device was found on Friday, Sept. 12 and determined to be real, FOX 13 reported.

Officials said the device had been lit but "failed to function."

The FBI’s Salt Lake City Field Office have assumed jurisdiction for the case.

The arrested duo are currently being held in  Salt Lake County Jail.

"FOX 13 News is working closely with law-enforcement and our risk management team, with the safety of our employees as our top priority," said FOX 13 Station Manager Leona Wood.
