Man accused of planting pipe bombs before Jan. 6 attack on Capitol charged with explosives offense

WASHINGTON (AP) — The FBI made an arrest on Thursday in its nearly 5-year-old investigation into pipe bombs placed outside the headquarters of the Republican and Democratic national parties in Washington on the eve of the Jan. 6, 2021, riot at the Capitol. He was charged with an explosives offense, prosecutors said.

The arrest marks the first time investigators have identified a suspect in an act that had long vexed law enforcement, spawned a multitude of conspiracy theories and remained an enduring mystery in the shadow of the dark chapter of American history that is the violent Capitol siege .
