The United States Secret Service detained a man Tuesday with a mysterious package outside the White House.
The Secret Service confirmed that the package was being examined and security parameters had been established.
The man had approached a uniformed officer at 15th Street and Pennsylvania Avenue — about a block from the White House — making "suspicious comments."
Tours in the East Wing of the White House have been suspended, but "all other activity continues as normal," according to the Secret Service.
This incident follows a string of threats to White House security this month, including a person who jumped over a bicycle rack near a security check point and a week before that, a California man who climbed over the White House fence and roamed free on the grounds for about 17 minutes.
