ABC News’ Matthew Jaffe & Z. Byron Wolf report: The US Capitol was momentarily put on lockdown today after a report of a man with a gun near an office building on the Senate side of the complex. The lockdown was lifted after only a few minutes and the all-clear was given. US Capitol Police said in a statement just after 11:30am that there had been a report of a man with a gun near 1st and Constitution Ave. NE and a suspect was now in custody. That location is just outside the Dirksen Office Building. Matthew Gagnon, an aide for Sen. Susan Collins, R-ME, posted a photo of the incident on Twitter.
Gagnon described the incident on Twitter. “Plain clothes cop in gray sweat-shirt is a hero. Totally took the guy down Ray Lewis style. Epic,” Gagnon tweeted. “Epic take down by the cops outside Dirksen. 5 seconds before officer had gun drawn,” he said.
