French political leaders have vowed justice and promised a crackdown after a shocking attack on a female police officer on New Year's Eve was filmed and posted online.
The attack in the eastern Paris suburb of Champigny-sur-Marne saw the officer knocked to the ground before being repeatedly kicked and punched in the head and body (see video below).
President Emmanuel Macron called the crime a "cowardly and criminal lynching", and vowed that those responsible would be caught and punished.
The incident took place in the early hours of New Year's Day after an emergency call out to a private party where huge hundreds had turned up and security were forced to turn hundreds away.
Police were called when a group of around 20 people, who refused to leave the event, broke into the warehouse where the party was taking place. The area was cleared by police.
They fired tear gas after "a group of particularly violent individuals laid into the police," local security chief Jean-Yves Oses said.
It's not clear what happened next but two police officers, one female and one male, became isolated among the crowd. Video images show youths turning over a police patrol car to cheers from crowds.
Then images show the policewoman knocked to the road and repeatedly kicked and punched.
Her colleague was also attacked and suffered a broken nose.
Two people were detained on suspicion of vandalism, but no one has been arrested for attacking the police.
On Tuesday, reports of another attack on police officers emerged, this time in the northern suburb of Aulnay-sous-Bois when police stopped two youths suspected of stealing a scooter.
One officer was punched several times while another fired his gun into the air to scare off the attackers.
The attacks on the police were widely condemned by France's outraged political class, who offered solidarity to the injured officers but also demanded swift and tough justice for those responsible. Far right leader Marine Le Pen demanded a reform to allow police to greater use of "legitimate defense" to respond to such attacks.
Pressure grew on France's interior minister Gerard Collomb, who called the attacks "savage" and "unacceptable".
He denounced a "society of violence" that "cannot continue to exist".
Collomb said reforms were needed to improve lives in "pauperised, ghettoised" French suburbs, which have long suffered a reputation for violence and poverty.
"These are neighbourhoods that must change," Collomb said, ahead of new pilot schemes in local policing set to begin next month following a large-scale consultation with security forces.
President Macron set out a raft of policies to fight poverty in downtrodden districts in November after critics labelled him a "president of the rich" due to his generous tax cuts for high earners.
He reached out to the poor again in his New Year's message, promising a "grand social project" in 2018.
But the two New Year's attacks on police are just the latest in a long line of incidents in which the forces of law and order have been targeted.
French police have long suffered testy relations with youths in poor immigrant-heavy suburbs, not least since the nationwide riots in 2005 sparked by the death of two teenagers who were electrocuted while hiding from officers.
The assault of a young man by police in Aulnay-sous-Bois -- which led to officers being charged, including for rape after a truncheon was shoved up the youth's anus -- sparked fresh unrest last year.
Politicians condemned the attack and police officers staged protests on the Champs-Elysées to denounce the violence.
“We want to fight against the trivialization of violence against the police,” one police officer in Nice told the Nice Matin newspaper at the time.
“We want to be heard by our hierarchy and by the judiciary. If we become victims ourselves, who will protect the public?
“We are under huge demand, but younger colleagues are being discouraged.”
Another police officer told the LCI news site: "We don't feel safe anymore so the French people don't either."
