The Secret Service apprehended a man who was trying to jump the fence on the south side of the White House Sunday.

Secret Service spokesman Tom Mazur identified the man as Roger Witmer, 44, of Washington, who faces charges of unlawful entry and disorderly conduct.

Mazur said members of the uniformed division captured Witmer before he got over the fence. But he threw over plastic bags, and officials shut down traffic on the south side of the White House so they could be examined for explosives. None was found.

President George W. Bush was out on bike ride in suburban Beltsville, Maryland, when Witmer was taken into custody. The Secret Service was examining the package when Bush returned, so his motorcade came detoured to an alternate entrance on the north side.
