The book, called "Combating Corruption", has so far been used to teach 30,000 civil servants not to take bribes, the Izvestiya newspaper reports . Created by illustrators from the state-run Moscow City University of Management, it features characters who are put in difficult situations, and offers advice on how to respond. There are also some cautionary tales of officials who have been caught in the act, the paper notes. One section tells officials that while they can accept gifts worth less than 3,000 roubles ($50; £30), they can't take such gifts regularly from the same person.
