The FBI on Friday increased its reward to $100,000 for information on those potentially involved in planting pipe bombs in Washington, D.C., the night before the Jan. 6 Capitol riot.
The FBI announced the new reward in a new poster shared to Twitter, up from the agency’s increase from $50,000 to $75,000 just last week.
The FBI on Friday also shared an image of an unidentified suspect, dressed in a face mask and gray hoodie, along with pictures of the suspect’s footwear, which authorities identified as Nike Air Max Speed Turf shoes in yellow, black and gray.
The poster added that the individual appeared to be carrying a backpack in their hand, with the agency including images of the devices found earlier this month.
Authorities now believe that the pipe bombs were planted outside the headquarters of the Republican National Committee and Democratic National Committee between 7:30 p.m. and 8:30 p.m. ET on Jan. 5.
The FBI is requesting that any information connected to the incident be reported either to the FBI’s tipline, or on the FBI’s website. Information can also be shared by contacting a local FBI field office, as well as an American Embassy or Consulate.
Both the FBI and the Bureau of Alcohol, Tobacco, Firearms and Explosives are still searching for at least one person who planted the devices.
Federal authorities have already charged more than 100 individuals in connection with the Jan. 6 Capitol riot, with investigators announcing Tuesday that they are currently looking into more than 400 potential suspects.
Acting U.S. Attorney for Washington, D.C., Michael Sherwin said on a call with reporters that law enforcement has received more than 200,000 tips from the public and obtained more than 500 search warrants and subpoenas.
