Paris police banned a protest on Saturday against violence by the force, a week after France was rocked by riots sparked by the killing of a teenager in a suburb of the French capital.
The Paris police department said in a decision published on its website that it had banned the planned demonstration on the Place de la Republique over risks to public order, citing a "context of tensions".
The police have come under scrutiny after the June 27 fatal shooting by a police officer of Nahel M at a traffic stop. The 17-year-old was driving a sports car without a licence.
Saturday’s protest was called by the family of Adama Traore, a Black Frenchman who died in police custody in circumstances similar to the killing of George Floyd in the United States.
The demonstration against alleged police violence and racial discrimination was initially planned as a march in Beaumont-sur-Oise, another Paris suburb, where Traore died in 2016.
