The French government vowed a crackdown on urban violence in reaction to the shocking video footage which emerged of a policewoman being attacked by a mob on New Year's Eve.

She was one of two officers attacked by the gang of youths after police were called to a party in the Paris suburb of Champigny-sur-Marne, in an assault President Emmanuel Macron called 'a cowardly and criminal lynching'.

Interior Minister Gerard Collomb called the attacks against police 'unacceptable', and said: 'This violent society cannot continue in the years to come. It must be stopped.'

Collomb said reforms were needed to improve lives in 'pauperised, ghettoised' French suburbs, which have long suffered a reputation for violence and poverty.

A third officer was beaten up Monday while trying to inspect a stolen scooter inside a sprawling housing estate in the suburb of Aulnay-sous-Bois.

More than a thousand cars were burned across France on New Year's Eve, a ritual among youths living in deprived high-rise suburbs. 

'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. 

Officers had been called to clear a crowd of three or four hundred people attempting to see in 2018 at a warehouse party in Champigny-sur-Marne.

They fired tear gas after 'a group of particularly violent individuals laid into the police,' local security chief Jean-Yves Oses said, with revellers beating and kicking two officers.

Videos of the policewoman writhing on the floor as she is kicked by the crowd, as well as revellers flipping over a car, have gone viral on social media.  

The unnamed police officer was filmed by gang members as she was kicked around by the attackers. The footage was then uploaded onto the internet by the group.

At one stage, her colleague appears so badly beaten up that he takes his gun out his holster, but does not let off a shot.  

The footage on social media has sparked outrage across France, with president Emmanuel Macron promising to bring the culprits to justice.
