The arrests were, however, not connected to the one-year anniversary of Al Qaeda chief Osama bin Laden's death. Instead, the suspects were described as anarchists, Xinhua reported citing local TV station WKYC. The FBI said the suspects had plotted to blow up the Cuyahoga Valley Scenic Railroad Brecksville Station near Cleveland.

They were arrested by the FBI's Joint Terrorism Task Force April 30 on charges of conspiracy and attempted use of explosive materials to damage physical property affecting interstate commerce. The FBI has filed charges against three of the suspects, who are self-proclaimed anarchists. Charges against two others are pending.
