A woman was arrested Monday after green paint was found splattered inside two chapels at the Washington National Cathedral, and police were investigating her in connection with two similar incidents on the National Mall, authorities said. The woman was arrested in the area of the cathedral shortly after the paint was found, Assistant D.C. Police Chief Peter Newsham said. Investigators were hoping to question her about the vandalism on the Mall, including at the Lincoln Memorial, but a language barrier delayed the interrogation, Newsham said.
