The FBI has shared a photo of the person responsible for placing the suspected explosive devices outside the Republican National Committee and Democratic National Committee Wednesday, prior to the U.S. Capitol protests.

On Thursday night, the FBI tweeted a photo of the suspect and posted a reward of up to $50,000 "for information leading to the location, arrest, and conviction of the person(s) responsible for the placement of suspected pipe bombs in Washington, D.C. on January 6, 2021."

The FBI tweeted a photo and posted a reward for information leading to the location, arrest and conviction of the person, or persons, responsible for the suspected pipe bombs found in Washington, D.C., on Jan. 6, 2020.

ABC News then obtained an exclusive photo of the suspected explosive device found outside the RNC, which is located just a couple blocks away from the Capitol.

A federal law enforcement source told ABC News that the suspected pipe bombs were indeed active, and U.S. Capitol Police confirmed that the devices could have caused "great harm."

"The USCP Hazardous Materials Response Team determined that both devices were, in fact, hazardous and could cause great harm to public safety," police said in statement.

Bomb technicians used water cannons to blast the devices to break them apart and render them harmless just as violent pro-Trump protesters broke though police lines and stormed into the Capitol.

The FBI has updated its poster about the suspected D.C. pipe bomber Monday. The new photos show the bomber’s distinctive backpack and shoes.
