People use Facebook as a way of meeting and keeping in touch with friends – or to chat about the world's most notorious mafia bosses.

Facebook pages prasing Cosa Nosta leaders are causing concern in Italy as they are attracting virtual fan clubs of young admirers.

Now some anti-mafia activists are calling for pages such as these to be banned.
