The White House was put on lockdown Monday afternoon after a woman threw an unknown object over the fence at the North Lawn, according to the Associated Press.
A woman was handcuffed and taken into custody after the object was thrown over the fence, near Pennsylvania Avenue, AP reported. The lockdown ended shortly before 4 p.m. ET, NBC News reported.
The lockdown began shortly after President Obama returned to the White House after a Memorial Day event at Arlington National Cemetery.
CBS White House correspondent Mark Knoller tweeted that a suspect had been detained and Hazmat teams were set to examine the package.

This is a breaking news story. We will provide updates as they are available.
Nothing on NBC, MSNBC, CNN, Washington Post or the local DC stations.
Sad to read this and wonder if the danger is from foreign terrorists or Republicans.
Another case of stupendous Trump-inspired stupidity?
Not being reported anywhere else
