The White House was reportedly put on lockdown Wednesday afternoon in response to a suspicious backpack.

“At approximately 2:45 pm an individual dropped a backpack and attempted to jump a bike rack along the sidewalk on Pennsylvania Ave. The individual was immediately taken into custody by Secret Service Uniformed Division Officers,” the U.S. Secret Service tweeted, adding, “Law enforcement officials are responding to the incident on the sidewalk of Pennsylvania Ave. Pedestrian traffic is closed along Pennsylvania Ave. between 15th and 17th streets to include Lafayette Park.”
