The suspect who planted two pipe bombs on Capitol Hill before the January 6 insurrection hasn't been identified, Metropolitan Police Chief Robert Contee said at a US House panel on Wednesday, according to The Associated Press.
The pipe bombs were planted outside separate headquarters for the Republican and Democrat national parties on January 5, but the bombs never detonated.
They weren't discovered until the next day, shortly before rioters in support of former President Donald Trump stormed the Capitol.
At a panel examining the federal response to the insurrection, Contee said investigators believe the suspect was a "lone individual," and four months after the riot, officials have not yet identified the person.
It's not immediately clear if the bombs were planted as part of the insurrection.
