A Pulitzer prize winner has been suspended from the Washington Post for plagiarizing, according to the news agency AFP.

Sari Horwitz, who along with a colleague won the Pulitzer in 2002 for reporting on foster children who died while under the care of child-welfare authorities, has been suspended for three months for plagiarizing parts of stories from the Arizona Republic about the shooting of U.S. Rep. Gabrielle Giffords, the New York Times said. A review of Horwitz's work did not reveal any other plagiarism.

The Washington Post published an apology saying that the newspaper's policy is to properly attribute content from any other newspapers or sources, and "the Post apologizes to the Arizona Republic and to its readers for this serious lapse."

Horwitz copied two paragraphs of one story and 10 of another, NPR explained.

The Editorsweblog points out that plagiarism is nothing new to journalism. In 2003, The New York Times' reporter Jayson Blair and several editors were fired after Blair lifted parts of stories.
