Five men have been arrested after allegedly conspiring to blow up a bridge about 15 miles south of Cleveland.

A CNN report says that Douglas L. Wright joined alleged co-conspirators Brandon L. Baxter a.k.a. "Skabby," and Anthony Hayne a.k.a. "Tony" and "Billy," in a plot that authorities say honed in on the Brecksville-Northfield High Level Bridge, which spans the Cuyahoga Valley National Park and carries a four-lane highway.

The men were arrested Monday evening in an FBI sting, but posed no real danger to the public because the explosives were inert and were controlled by an undercover FBI agent, the bureau said in a statement.

The men have been charged with conspiracy and attempted use of explosive materials to damage physical property affecting interstate commerce.

Connor C. Stevens and Joshua S. Stafford were also arrested. Their charges remain pending.

The report said at least three of the men are self-proclaimed anarchists who had considered "a series of evolving plots over several months."

The men allegedly conspired to acquire C-4 explosives and build two improvised explosive devices to be remotely detonated.

At first, officials said, the men had considered using smoke grenades to distract local law enforcement in an effort to "topple financial institution signs atop high rise buildings," the report said.
