A Moroccan man who was arrested in an alleged plan to bomb the U.S. Capitol building was not carrying explosives, as the materials in the vest had been rendered inoperable by law enforcement, U.S. Justice Department spokesman Dean Boyd said on Friday.
At the time of the arrest, police officials indicated that the man was planning a suicide bombing attack on the Capitol.
The man had on his person what he thought was a vest with explosives, but the materials in the vest had been rendered harmless, Boyd said.
The man had been monitored as part of a lengthy undercover operation, and U.S. Capitol Police had been closely involved in the investigation, police officials said.
The man was not connected to a terrorist organization, and was acting alone, police said.
