French police have arrested a man they say was in the "advanced stages" of a plot to attack the country.
French Interior Minister Bernard Cazeneuve said the suspect was arrested Thursday in the Argenteuil neighborhood northwest of Paris.
He said there was "no tangible evidence linking the plot to either the attacks in Paris or Brussels."
Cazeneuve said bomb squads were on the scene and the area was under a lockdown.
France has been on high alert since the November 13 attacks in Paris that killed 130 people and injured hundreds. Cazeneuve said there have been 75 arrests since the beginning of the year, and 28 suspects have been jailed.
