Among those detained was Claude Hermant, an ex-mercenary known for his extreme right-wing links, according to the reports. Six months before the Paris attacks he and his wife purchased arms from a Slovakian company, which were found in Coulibaly's possession after the attack on the supermarket.
During the interrogation in 2015, Hermant claimed he was an informant on arms trafficking for the French police.
In early January 2015, terrorists attacked the office of Charlie Hebdo, a magazine notorious for publishing caricatures of the Prophet Muhammad, and a kosher food supermarket, killing a total of 17 people.
