Franceinfo, a French domestic rolling news channel, reported this on Saturday.
The two suspects, aged 30 and 45, were believed to have planned an action against President Macron during the commemoration of the centenary of the end of the First World War, in Nov. 2018, said Franceinfo quoting a Parisian judicial source.
The two were arrested Monday in Moselle, northeastern France.
They had been presented to an examining magistrate for their indictment.
The national anti-terrorist prosecutor’s office had requested their detention on remand.
