"The arrested individual, a French national, is suspected to be involved at a high level in a terrorist network that planned to strike France," the minister said as quoted by Le Figaro on Friday.
On Thursday, French police foiled a terrorist plot in Argenteuil, arresting one suspect.
"The arrest is the result of a careful investigation for several weeks," Cazeneuve said at a press conference, adding that the suspect was involved in a planned attack that was in advanced stages of development.
The building where the suspect lived was evacuated. Police conducted a broad search in the area, establishing a safety perimeter and blocking access to the General Delambre boulevard in Argenteuil, located in the Val-d'Oise department.
According to Cazeneuve, there appeared to be no link between the arrest in Argenteuil and the Brussels terrorist attacks.
On Tuesday, two suicide blasts hit the Brussels Airport and the Maelbeek metro station in the city, killing at least 31 people and injuring over 300.
The Islamic State (ISIL) jihadist group, outlawed in a range of countries, including Russia, claimed responsibility for the attacks.
