France saw a jump in arrests on New Year's Eve as well as an increase in the number of cars torched by vandals, a ritual among revellers in the country's high-rise suburbs.
French President Emmanuel Macron took to Twitter to denounce the "cowardly and criminal lynching of police officers doing their duty" and warned that the culprits would be "found and arrested".
"I regret that incidents like yesterday can happen but overall people were able to enjoy New Year's eve in a peaceful manner," Interior Minister Gerard Collomb said Monday.
Some 140,000 security and emergency forces were deployed across France on New Year's Eve.
The ONDRP's Christophe Schulz told Le Parisien newspaper that there are diverse reasons that youths burn cars.
