FBI releases surveillance video with map that shows the route the D.C. pipe bomber took.

WASHINGTON, DC — The FBI released a new surveillance video of the person wanted for planting pipe bombs outside the headquarters of the Republican National Convention and the Democratic National Convention the night before the Jan. 6 insurrection at the U.S. Capitol.

Between 7:30-8:30 p.m. on Jan. 5, an unknown person walked through the Capitol Hill neighborhood and placed a pipe bomb in an alleyway behind RNC headquarters (310 First St., S.E.). They then walked to the area of DNC headquarters (430 South Capitol St., S.E.) and left a pipe bomb next to a park bench nearby.

Throughout the endeavor, the person wore a face mask, glasses, gloves and a gray hooded sweatshirt, according to the FBI. He also wore black and light gray Nike Air Max Speed Turf shoes with a yellow logo and carried a backpack.

The surveillance video, which the FBI posted on YouTube, also recreates the route the suspect followed when placing the bombs.

The FBI and ATF are offering a reward of up to $100,000 for information that leads to the arrest and conviction of persons responsible for placing the two bombs on Jan. 5.

"The FBI is extremely grateful to the American people who have already provided us with vital assistance in this cast," FBI's Assistant Director in Charge Steven M. D'Antuono said, in a statement." Since January, the FBI has conducted more than 800 interviews, collected more than 23,000 video files, and assessed more than 300 tips related to this investigation. Those tips have helped us uncover new information, which we are releasing today and asking the public to view it and cull us with any information you think may be relevant."

Anyone with information about this incident is asked to call the FBI's toll-free tip line at 1-800-CALL-FBI (1-800-225-5324) or submit tips to fbi.gov. Tips may also be submitted via your local FBI officer or nearest American embassy or consulate. Tips may be submitted anonymously.

"We know it is hard to report information about a friend or family member, but these pipe bombs were viable devices that could have detonated, causing innocent bystanders to be seriously injured or killed," D'Antuono said. "Your tip could be the one that prevents this person from harming themselves or anyone else."
