Armed man attempts to breach FBI field office in Cincinnati, authorities say

State highway patrol troopers and local law enforcement agents responded Thursday morning to an apparent attempt by an armed suspect to breach the FBI field office building in Cincinnati, Ohio. 

Details on the situation are still unfolding. Authorities confirmed publicly that the incident took place around 9 a.m. local time, prompting them to shut down roughly a one-mile stretch of a nearby highway and issue a lockdown warning for residents and businesses in the surrounding area. 

The suspect, who has not yet been otherwise identified, raised alarms by allegedly attempting to break in through the visitor screening center, according to a message posted by the FBI Cincinnati Twitter account several hours after the incident. The FBI said the individual fled following an immediate response from special agents, and began traveling north on Interstate 71.
