The AFP news agency quotes the Paris prosecutor as saying that one of the bombers had previously been placed under formal investigation for a "terrorism" offence.
The Paris prosecutor has identified two of the suicide bombers in Friday's attacks as Ahmad Al Mohammad and Samy Amimour.
Al Mohammad blew himself up at the Stade de France. He was born on 10 September 1990 in Idlib, Syria, if the passport found near his body was authentic.
Amimour was one of the suicide bombers at the Bataclan theatre. He was born on 15 October 1987 in Paris. He lived in the north-eastern suburb of Drancy.
