The Federal Bureau of Investigation (FBI) announced on Saturday that it would raise the reward to $100,000 for information about who placed the two bombs near the headquarters of the Democratic and Republican parties on January 6, in addition to issuing new details and photos of a suspect.

US media reported that the bombs were eight inches long, connected to timers, and filled with explosive powder. The authorities investigating the remnants of the devices at the FBI laboratory in Virginia expressed concern that the detonator was still in operation.

The federal government has charged more than 100 people, according to a census drawn up by the Program on Extremism at George Washington University, and they are 102 men and 15 women who came from 35 US states and Washington, DC.

On the other hand, US law enforcement agents found bomb-making instructions inside the home of a member of the Proud Boys right-wing extremist group who was charged with participating in the Jan. 6 siege of the Capitol, prosecutors said on Friday.

Dominic Pezzola, 43, had "weapons- and bomb-making manuals" on a thumb drive device found within his home near Rochester, New York, prosecutors said in a court filing arguing that he should be jailed pending trial.
