The White House was on lockdown Tuesday evening after a man jumped the fence on the North Lawn, the Secret Service tells Fox News.

James Dirk Crudup, 41, was taken into custody and charged with unlawful entry and attempted contempt for violating a stay away order at the White House.

Crudup, who is homeless, was then taken to the 1st District precinct after he was processed in the main booth of the grounds.

Secret Service Spokesperson Edwin Donovan said Crudup had a backpack that was being examined for possible explosives.

Several armed Secret Service agents were spotted on the scene.
