The White House lockdown was lifted after about one hour on Tuesday afternoon (local time) after police established that an unattended package found on the outside of the north fence line was not hazardous.
The US Secret Service confirmed the clearance of the unattended package near the north fence line of the White House Complex.
In a tweet, The US Secret Service stated, " @SecretService and @DCPoliceDept have cleared the unattended package near the north fence line of the @WhiteHouse Complex."
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 Secret Service said pedestrians and others were cleared from the area along Pennsylvania Avenue.
After investigating, a spokeswoman for the U.S. Capitol Police said no hazards were found, but a man was arrested and charged with unlawful entry in the restricted zone.
