A man who hopped a fence near the White House grounds Tuesday, prompting a security lockdown, was fleeing after stealing a woman's purse, officials said.
The lockdown began at around 4 p.m. and was lifted by around 4:30 p.m. The Secret Service said the White House was placed under a state of lockdown called a "condition yellow."
Tourists were cleared from Lafayette Park, which is directly north of the White House.

The Secret Service said the man jumped the fence at the Eisenhower Executive Office Building at 3:55 p.m. and was taken into custody without incident.
It doesn't appear that the man had any idea he was hopping a fence to the White House complex, the official said.
"Initial investigation indicates the individual was fleeing from the scene of a robbery," the Secret Service said in a statement.
The building is west of the White House, and the man got nowhere near a fence separating that area from the White House grounds. D.C. Fire and EMS said the man was being taken for an evaluation.
