The FBI made an arrest on Thursday in its nearly five-year investigation into the individual who placed pipe bombs in Washington on the eve of the January 6, 2021, riot at the U.S. Capitol, as confirmed by a law enforcement official to The Associated Press. This marks the first time investigators have identified a suspect in a case that has puzzled law enforcement and fed numerous conspiracy theories since the events of that fateful day.

The specifics of the arrest, which occurred on Thursday morning, remain largely undisclosed, including the identity of the suspect and the potential charges they may face. The pipe bombs, which were located on January 5 near the Democratic and Republican national committee offices in Washington, could have resulted in deadly outcomes but ultimately did not cause any injuries.

In the years following the incident, the FBI sought public assistance to identify the suspect, captured in surveillance footage, while struggling to ascertain key details about the individual, such as gender and motive, and whether the actions were linked to the subsequent Capitol riots initiated by supporters of then-President Donald Trump in response to the certification of Joe Biden's 2020 election victory.

Despite extensive review of video footage, hundreds of tips, and interviews, the bureau faced challenges in isolating a suspect until recent developments led to the identification and arrest. This progress is anticipated to shed light on an event surrounded by speculation and intrigue, especially as various political factions have sought to reinterpret the narrative surrounding the Capitol riots and subsequent security oversights.

FBI officials had previously announced an increased reward for information about the case, and they pledged to prioritize this significant investigation, aimed at finally closing a dark chapter related to the January 6 attacks.
