The FBI on Thursday released a new video allegedly showing the Jan. 5, 2021 suspect who planted pipe bombs outside the Democratic National Committee and Republican National Committee offices in Washington, D.C. 

Along with the video, the FBI also revealed that the suspect is believed to be about 5-foot, 7-inches tall in an effort to elicit new tips from the public ahead of the fourth anniversary of the crime. 

The FBI noted that a $500,000 reward is still available for tips that lead to an arrest. 

The attempted attack occurred on the eve of the Jan. 6, 2021, attack on the U.S. Capitol, but there is no clear link between the two events. 

The suspect then placed the second bomb in an alley behind the Republican National Committee building at around 8:16 p.m. and was last seen in surveillance footage two minutes later walking past a row of D.C. houses wearing a backpack that investigators believe they used to transport the pipe bombs. 

“We still believe there is someone out there who has information they may not have realized was significant until now,” the narrator of the FBI video said. “We’re asking you to come forward and share that information with the FBI.” 

No one was hurt in the attempted attack and the bombs were rendered safe, but the FBI said it could have been deadly. 

Both Vice President Kamala Harris and then-House Speaker Nancy Pelosi were near the DNC office before the first bomb was found on the afternoon of Jan. 6 and deactivated.
