Up to a third of Malta's prison population is made up of people who have been jailed for offences involving false passports. Some 250 people are currently behind bars for such offences. Whilst sentencing a Moroccan national to six months for use of a false passport, a magistrate recently said "that new facilities would need to be built to accommodate such offenders if the trend continued," and said there was a "dire need for a European and International mechanism for dealing with such cases."
