Police in France have jailed a 20-year-old Tahitian after he was suspected of wanting to commit a terror act in France.
The man, who lives in the eastern town of Besancon, was imprisoned after an anti-terror judge charged him with being linked to a criminal terrorist group.
French media said under emergency laws now in force, he had been questioned behind closed doors last week.
That cleared the way for his computer to be seized, and established he was a follower of a fugitive French jihadist Rashid Kassim, who encourages terror attacks in France.
