JACKSONVILLE, Fla. — Students at the University of North Florida have been given the all clear to leave campus after police responded to a report of an armed individual on campus Monday night.

A UNF spokesperson said UNF police and the Jacksonville Sheriff's Office did a thorough search of the Arena garage and found that a call made about an armed individual was "not credible."

Both JSO and UNF police will remain on campus for the rest of the evening and will work to determine the source and reasoning behind the initial call. An armed person has not been found and no additional reports have been made.

Classes at UNF remain canceled as police investigate.

A UNF spokesperson said someone reported to the Jacksonville Sheriff's Office after 6 p.m. that they saw a person with a gun at the Arena garage.

JSO then alerted UNF, who had their own police department investigate the report. 

UNF said no other person has reported seeing an armed individual.

The university said an alert about the report was sent to students at 6:12 p.m. however some students have told First Coast News that they did not receive a text until 7:05 p.m.

Official alert message from UNF: 

UPD is responding to a possible armed individual in garage Building #38. Leave the area if safe to do so.  Find a safe area and shelter in place.

Officers have blocked Building #38 until further notice.  Do not attempt to enter or leave Garage #38 next to the Arena.
