A 29-year-old man was arrested in the Paris region on Tuesday as part of the vast investigation into last month's attacks on the city that left 130 dead, a judicial source said, according to the AFP news agency.

The probe has seen 2,700 police raids and 360 people placed under house arrest since the attacks by the Islamic State (ISIS) group, which triggered a nationwide state of emergency.

The man detained Tuesday is to be questioned about possible links with another man who is believed to have left for Syria and who is of particular interest to police investigating the November 13 attacks, a source close to the case said.

The suspect lives in a housing estate in the eastern Paris suburb of Villiers-sur-Marne.

The town's mayor, Jacques-Alain Benisti, said the man lived with his mother and "had a job". A source close to the mayor also said he frequented a prayer room run by the ethnic Tamil community.

Two men are already in custody, accused of providing accommodation to Abdelhamid Abaaoud, the suspected ringleader who was killed in a major police raid in northern Paris five days after the attacks.

Abaaoud, a Belgian national of Moroccan origin who boasted of the ease with which he had re-entered Europe from Syria via Greece two months before last month’s attacks, was reportedly also planning to attack Jewish targets and disrupt schools and the transport system in France.

Eight men have been arrested in Belgium, where the attacks are thought to have been organized, and one man has been detained in Turkey on suspicion of scouting the concert hall, bars and restaurants where the attacks took place, AFP reported Tuesday.

Six counter-terrorism judges are overseeing the investigation -- an unprecedented number for France.

But three of the nine attackers have yet to be identified, including two of the three suicide bombers who blew themselves up outside the Stade de France stadium, who appear to have used fake passports to sneak into Europe posing as refugees.

The other unidentified man is thought to have taken part in the gun attacks on the terraces of restaurants and bistros and died alongside Abaaoud in the shootout with police on November 18.

Salah Abdeslam, a 26-year-old French citizen is thought to have played a key logistical role, is still on the run and subject to an international arrest warrant. It has been speculated that he fled from Belgium to Germany.

France’s Interior Minister Bernard Cazeneuve said Tuesday a total of 334 people had been arrested since the attacks, of whom 287 were held for questioning, and that over 400 weapons had been seized.

Some 1,800 French citizens have been linked to jihadist networks, the minister said, including more than 600 who are currently in Syria and Iraq and 144 had died in fighting there.

He said 250 had returned to France, while around 500 were "preparing to leave" and the rest already in transit.

Separately, two men were also being questioned on Tuesday in relation to the attacks in January on the French capital that targeted Charlie Hebdo magazine, police and a Jewish supermarket.
