A 29-year-old man has reportedly been arrested in relation to the Paris attacks, while two more suspects are being questioned in connection with January’s atrocities in the city.
France's iTele cited an anonymous source in its report, saying the suspect linked to last month’s massacres was arrested in the Paris region.
Also on Tuesday, two people were detained in a separate investigation into the previous Paris attacks in January.
A man and a woman are being questioned over weapons used by Amedy Coulibaly, who killed four hostages before being shot dead by police at a kosher supermarket.
The prosecutor's office confirmed that the man is Claude Hermant, an alleged arms trafficker linked to the extreme-right, while the other is said to be his partner.
Coulibaly proclaimed support for Isis and was allegedly in contact with the Kouachi brothers, who were on the run after carrying out the Charlie Hebdo massacre, threatening to murder hostages if they were harmed by police.
Around 2,700 police raids have been conducted since the latest wave of attacks, with an estimated 360 people currently under house arrest in France.
Two men have already been charged with aiding the alleged “mastermind”, Abdelhamid Abaaoud, by providing accommodation.
Eight men have also been arrested in Belgium, where the shootings are thought to have been organised, and another Belgian man was detained in Turkey on suspicion of scouting out the targeted concert hall, bars and restaurants.
Three of the suspected nine attackers have still not been publicly identified, while Salah Abdeslam remains on the run.
