WASHINGTON (Reuters) - Police were investigating reports on Tuesday of suspicious packages at three locations in the U.S. capital, including one near the White House that was later determined to be harmless, officials said.
Authorities blocked off some streets around the White House because of a parcel lobbed by a homeless woman into the courtyard of an office building adjacent to the presidential mansion, the Secret Service said.

The other locations were by Union Station, where Amtrak and commuter rail services operate, and by a Coast Guard facility and bomb squad teams were responding, Washington police spokesman Josh Aldiva said.
