An unarmed man climbed over the White House's 10-foot fence today and was seized by Secret Service agents.

The man, Andrew Meig Jopling, 24, was charged with unlawful entry. The authorities said Mr. Jopling told them that he was born in Annapolis, Md., but had no permanent address.

A Secret Service spokesman, Mike Tarr, said Mr. Jopling scaled the fence along East Executive Avenue directly in front of the East Wing entrance to the White House.

"He jumped over the fence and was immediately apprehended," Mr. Tarr said.

The site was near where tourists were lined up for tours of the White House. Numerous Secret Service agents are normally stationed in the area.
