Police report shots fired on the west front of the Capitol in Washington and say the building has been locked down as a precaution.

Spokeswoman Kimberly Schneider of the Capitol Police says in a statement that the suspected shooter has been "neutralized," but there is no immediate explanation what that means.

She also says the Capitol Police are investigating a suspicious package on the lower west terrace of the building.

No one is being allowed to enter or exit the Capitol and the visitors center.

Congress has been on spring break for two weeks and lawmakers are set to return to work Monday.
