Nearly 250 people clashed with police firing tear gas in a Paris suburb, in apparent protest over enforcement of France's ban on Islamic face veils.
Outraged crowd threw stones at French police and set fire to cars in the second night of disturbances in Trappes.
According to the BBC, the protests began after a man was arrested whose wife was told by police to remove the veil, which was banned in public.
He has been accused of trying to strangle the officer. Up to 300 people attacked a police station in Trappes on Friday night where the man was being held.
The ban on wearing the full face veil in public was introduced in April 201.
In the latest violence which erupted in Trappes and several neighbouring areas, bus-shelters and cars were torched and fireworks directed at police, the report added.
