The man was allegedly carrying an AR-15 and shooting into the building with a nail gun.
“At approximately 9:15 EST, the FBI Cincinnati Field Office had an armed subject attempt to breach the Visitor Screening Facility (VSF),” FBI Cincinnati said in a statement. “Upon the activation of an alarm and a response by armed FBI special agents, the subject fled northbound onto Interstate 71.”
At about 12:30 p.m. local time, the agency said the suspect was “contained” but not in custody, according to a report from NBC News.
The suspect took off on I-71 towards Columbus and the pursuit eventually ended near W. State Route 73, according to a report from Fox 8.
During the chase, the highway was shutdown in both directions as multiple agencies attempted to apprehend the suspect.
All buildings within a one mile radius of the FBI headquarters were also placed on lockdown.
The armed man was reportedly making threats as he attempted to breach the building, but it is not clear what those threats were at this time.
According to reports over the police scanner, the suspect was a “white male.” He was allegedly wearing a grey shirt and body armor.
“Blood splatter on his shorts. Right thigh area,” an officer in a police helicopter said over the radio, according to a report from the News Journal. “Part of windshield shot out … Suspect on knees, holding rifle.”
“Rifle down for the moment. He is on his knees,” an officer said over the scanner at 10:24 a.m. local time.
The incident is taking place just days after the agency raided Donald Trump’s residence at Mar-a-Lago.
FBI director Christopher Wray has claimed that there have been threats against him and agents in the aftermath of the raid.
“I’m always concerned about threats to law enforcement,” Wray said during a news conference on Wednesday. “Violence against law enforcement is not the answer, no matter who you’re upset with.”
This situation is ongoing and this story will be updated as more information becomes available.
UPDATE: The suspect was killed in the pursuit.
