Look for inmates growing beards, reading religious books and not wanting to share showers with non-Muslims. That is the advice given by security officials from several European countries in a manual to help prison authorities spot potential terrorists.
The manual, developed by France, Germany and Austria, was released to help prevent prisons from becoming breeding grounds for Muslim extremists. The document was distributed at a two-day closed-door conference of European security experts this week. It will also be given to prison personnel.
