WASHINGTON (NewsNation Now) — The FBI released more photos on Monday of a possible suspect related to placing pipe bombs at the Republican National Committee and Democratic National Committee headquarters last week.

The bureau announced last week that they were offering a reward of up to $50,000 for information leading to the location, arrest and conviction of the person(s) responsible.

If you have any information concerning these incidents, the FBI says to contact a tip line at 1-800-CALL-FBI (1-800-225-5324), or submit tips online at fbi.gov/USCapitol.

The pipe bombs were placed amid the backdrop of riots at the U.S. Capitol.
