A lockdown of the White House was lifted after about an hour Tuesday afternoon after police determined that an unattended package found near the north lawn was not hazardous, the U.S. Secret Service said.

Police said the item had been discovered about 1:15 p.m. in an area along Pennsylvania Avenue and Lafayette Square, just outside the security perimeter. Pedestrians were cleared from the area between 15th and 17th streets.

A spokesman for the U.S. Secret Service said the package was determined harmless about 2:15 p.m. The owner has not been located.

The incident came a few minutes after police found a different suspicions package at 1:10 p.m. on the Rotunda steps of the U.S. Capitol.

A U.S. Capitol Police spokeswoman said no hazards were found, but a man was arrested and charged with unlawful entry; the steps are off-limits to the public.
