FBI opens 160+ investigation cases against Capitol Hill rioters

The agency has worked with the US Attorney's Office and law enforcement partners in DC and across the country to arrest and charge multiple individuals who took part in last week's breach of the US Capitol, D'Antuono told reporters at a news conference.

He added the FBI will be knocking on the doors of the people who participated in the attack on the Capitol.

In the weeks leading up to the rally, the FBI developed intelligence about a number of individuals planning to travel to the DC area with violent intentions.

The information was shared, and Enrique Tario was consequently arrested by the Metropolitan Police Department the night before the rally.

"Other individuals were identified in other parts of the country and their travel subsequently disrupted," D'Antuono noted.

Acting US Attorney for the District of Columbia, Michael Sherwin, said the scope and scale of the investigation are unprecedented not only in FBI history but also in the Department of Justice's history, in which the Capitol grounds are essentially crime scenes.

Noting this is going to be a long-term investigation, he said 170 cases have been opened currently but the number might grow.

Meanwhile, Sherwin said two pipe bombs were also found outside the RNC and the DNC offices near the Capitol grounds.

"They were real devices. They had explosive ignitors...We don't know exactly why they did not go off. That's being investigated. They were destroyed, disabled by Capitol Police with the assistance of the ATF, and that is all obviously being vetted and investigated."

The FBI has announced a reward of $5,000 for any information leading to the identification of the individual or individuals that left the pipe bombs.

Federal prosecutors are looking at everything from simple trespass and theft of mail and digital devices inside the Capitol, to assault, murder, and theft of potential national security information or national defense information.
