Police shut down a major Metro stop near the Capitol on Friday after a person was found stabbed.

The victim, who has not yet been identified, approached a station manager on the mezzanine level of the Capitol South Metro station and collapsed, said Dan Stessel, a Metro Transit police spokesman. Police do not have a suspect in custody yet, but are looking for a 14-year-old girl.

Metropolitan Police, Capitol Police, Metro Transit Police and medics are all on the scene.

Capitol South is the station frequented by aides who work on the House side of the U.S. Capitol. It's across the street from the Capitol Hill Club — a private Republican social club — and down the road from the Capitol and the three House office buildings.
