A "flying squad" of the Election Commission swooped down on a bookshop in Chennai on Tuesday and seized copies of a book on the Rafale allegations just before its launch. The officials said the book, "Rafale: The Scam That Shook the Nation", was a violation of the code of conduct in place for the national election starting April 11. Reports suggest around 150 books, written by engineer S Vijayan, were taken away by the "poll squad" from Bharathi Puthakalayam, a bookshop and publishing house linked to the CPM. An official on the "squad" referred to a letter on a plain paper with no official stamp directing the publishers to cancel the release of the book.
