French police arrested two men and a woman Tuesday in connection with last month's terrorist massacre in Paris and the attacks in the city in January, judiciary officials said.
One of the two men detained in Villiers-sur-Marne, to the east of Paris, is deemed a "peripheral" suspect over the Nov. 13 atrocity, judiciary sources told Reuters.
The woman and the other man arrested are suspected of supplying weapons to Amedy Coulibaly, who killed a policewoman and then four other people at a kosher store in January, the sources said.
The January attack took place on the heels of another in which two Islamist militants killed 12 people at the offices of the satirical newspaper Charlie Hebdo, which became a target after publishing mocking cartoons of the Prophet Mohammad.
France remains on top security alert since the Nov. 13 attack - the deadliest on French soil since World War Two. At least eight gunmen and suicide bombers killed 130 people at cafes, a concert hall and near the Stade de France national sports stadium.
Seven assailants died in that attack and an eighth in police raids days later, but police are still searching for another chief suspect, Salah Abdeslam, who vanished after escaping to Belgium from Paris.
Separately, a teacher who claimed to have been stabbed by a man on Monday acting in the name of ISIS was hospitalized after admitting to police that he had invented the story, prosecutors said.
ISIS, which claimed responsibility for the Nov. 13 attacks, has stated that teachers in France's secular state-schooling system should be killed for promoting what it called the evils of secular life, music and drawing.
