French Main Directorate of Internal Security law enforcement arrested six as part of an investigation into threats against the country's president Emmanuel Macron, BFM TV reported. The suspects are allegedly linked to radical movement, the media specified.
The arrests were reportedly made in the departments of Ille-et-Vilaine, Isère and Moselle.
According to BFM TV, during the searches at the apartments of the arrested persons, the law enforcement found a 45 caliber pistol and detonators from grenades at the place of the suspected leader of the group.
Paris prosecutors began a preliminary investigation into the allegations.
As AFP reports, citing officials, those arrested had an imprecise and loosely-formed plan for "violent action" against the French president. According to the agency, the suspects were between 22 and 62 years old and included one woman. However, it is not unclear if they had been working together.
"This investigation is looking into a plot, vague and ill-defined at this stage, involving violent action against the president of the republic," an official, quoted by AFP said.

Law enforcement has yet to comment on these reports.
At the end of July last year, the law enforcement arrested a 23-year-old man who tried to kill Macron at France's Bastille Day military parade, along with "Muslims, Jews, blacks and homosexuals."
Also last year, French police have arrested ten radicals suspected of plotting to kill Macron's spokesman Christophe Castaner, leftist leader Jean-Luc Mélenchon and to launch attacks on migrants and mosques.
