March 10 (UPI) -- The FBI has released a new video and additional information about the person sought in connection to pipe bombs placed near the headquarters of both the Democratic and Republican parties in Capitol Hill a day before insurrections stormed the Capitol building.
In the video, released Tuesday, a person wearing a gray hoody and carrying a backpack is seen in four separate security camera footage walking around the Capitol Hill neighborhood of Washington, D.C.
The FBI said the pipe bombs were planted between 7:30 p.m. and 8:30 p.m. on Jan. 5, a day before supporters of then-President Donald Trump stormed the Capitol building in a failed attempt to prevent the certification of President Joe Biden's November election win.
One pipe bomb was found next to a park bench near the headquarters of the Democratic National Committee and the other was found in an ally behind the Republican National Committee facility, authorities said.
The video footage release Tuesday shows the person sitting on a park bench near the DNC building and walking down an ally adjacent to the RNC facility.
The FBI said it is asking the public for help to identify this individual.
"These pipe bombs were viable devices that could have been detonated, resulting in serious injury or death," Steven M. D'Antuono, assistant director in charge of the FBI's Washington Field Office, said in a statement. "We need the public's help to identify the individual responsible for placing these pipe bombs to ensure they will not harm themselves or anyone else."
The FBI had earlier released photos of the person, stating he wore a mask, a gray hooded sweatshirt and black and light gray Nike Air Max Speed Turf shoes, and that a backpack was used to carrying the bombs.
The bureau called on the public to watch the videos in case someone recognizes the individuals gait, body language or mannerisms. It has also offered with the Bureau of Alcohol, Tobacco Firearms and Explosives a $100,000 reward for information that leads to the person's identification.
"We still believe there is someone out there who has information they may not have realized was signifiant until now," D'Antuono said. "We know it can be a difficult decision to report information about family or friends -- but this is about protecting human life."
