In France, a fiche "S" is an indicator used by law enforcement to flag an individual considered to be a serious threat to national security. The "S" stands for Sûreté de l'État. It is the highest level of such a warning in France; it allows surveillance but is not cause for arrest. There have been some 400,000 individuals assigned a fiche "S" since 1969. These continue to include gangsters, prison escapees, and ecologists, as well as suspected Islamist radicals. Suspects flagged with fiche "S" have included those who have looked at jihadist websites or met radicals outside mosques, to those considered highly dangerous.
