Capitol Police, D.C. police and the Federal Bureau of Investigation responded to a bomb threat near the Capitol campus Saturday night.

The incident occurred in the 400 block of New Jersey Avenue NW around 10 p.m. Saturday evening, according to D.C. police spokesman Officer Anthony Clay.

Police “apprehended a person that had a suspicious package, who was walking around talking to himself,” Clay said.

According to a Capitol Police officer privy to the incident, officers responded to a call from a hotel where a Middle Eastern man was reported to be in the lobby, talking to himself.

“He would not talk to the police when they asked him questions,” the officer said. “He had a large backpack with him in the lobby; once they got him into custody they had the bomb squad come in to check the package.”

A section of New Jersey Avenue was blocked off during the incident. It is not known what was found in the backpack, but no hazardous material was discovered at the scene.

The suspect was in police custody by 10:20 p.m. and was placed under evaluation, said Clay.
