Forty-six people were taken into custody in Paris on Saturday in connection with banned protests by far-right and anti-fascist groups, police told AFP.
They were among 97 people arrested in several areas in the centre of the French capital, according to updated police figures.
Police had banned a protest organised by the far-right May 9 Committee and an anti-fascist counter-demonstration called "No Nazis in Paris" that had been due to take place on Saturday afternoon.
A court upheld the ban due to the risk of public disorder.
Over the course of the day, 182 people were fined for failing to comply with the ban order.
