Police across France have held symbolic protetsts of throwing their handcuffs to the ground in angry response to claims that they tolerate brutality and racism, reports BBC News.
Protesting police also drove in convoy down the Champs-Élysées in central Paris on Friday, sounding their horns.
They rejected any parallels with the Minneapolis police officers whose fatal arrest of George Floyd sparked a wave of anti-racism protests worldwide.
And they are furious with a government ban on the police "chokehold".
Interior Minister Christophe Castaner announced the ban on Monday, after French protesters took to the streets alleging that police in France exhibited racism towards ethnic minorities, in the same way that US police have been accused of using brutality towards black suspects.
Mr Castaner held talks with police unions on Thursday and they are continuing, as the government seeks to cool an intense racism debate that has re-ignited tensions in some communities.
There was trouble earlier this month when protesters, inspired by the US anti-racism marches, commemorated Adama Traoré, a 24-year-old black Frenchman who died in a 2016 police operation.
Police have also been accused of seriously wounding a 14-year-old boy called Gabriel, when he was detained on suspicion of trying to steal a scooter in Bondy near Paris late last month.
Anti-racism activists plan to march from République to Opéra in central Paris on Saturday. The Paris police department has warned that shops and other businesses in the area should close and board up their windows, as trouble could flare up again.
Police handcuff protests took place on Thursday in Paris, Lille, Rennes, Bordeaux, Toulouse and other cities and continued on Friday morning, with a row of officers discarding their handcuffs at Orly airport near Paris.
Defending the police use of chokeholds, Xavier Leveau of the police union told the AFP news agency that "head restraint is very important during handcuffing". He insisted it was nothing like the method used in the death of George Floyd.
"We're not going to hold him down for eight minutes, we're going to hold him down just for the handcuffing... we don't have a substitute technique. So how do we do it today?"
