The Secret Service says a man has been arrested after he climbed over a fence at the White House.

Secret Service spokesman Brian Leary says the man climbed over the fence around 4 p.m. Sunday and was immediately arrested. The White House briefly went into lockdown after the incident, which is standard procedure.

The Secret Service did not immediately release the identity of the man, and Leary said charges were pending.

Obama returned to Washington on Saturday after a weeklong trip abroad.
