The World War Two memorial in Washington was vandalised with bubbly soap and graffiti on Thursday, prompting vows from the U.S. government to find the perpetrator.
The fountain bubbled over with suds and someone painted "Clean hands Dirty $" on one surface, splattering the area with red and green paint. Uniformed police and National Guard troops converged on the scene, which was cordoned off with yellow crime scene tape, keeping visitors away.
