At the beginning of May, drug seizures and the arrest of a suspected dealer had set fire to the powders in the district of La Frayère, west of Cannes.
Several nights, incidents had broken out with the police.
And the storefront of a municipal police station had been set on fire.
The city, which has become a civil party, indicates on Monday that "one of the individuals responsible for this violence" has just been sentenced to six months in prison.
"Identified on the images recovered by the municipal video protection center", he was also ordered to pay more than 15,000 euros to the town hall for material damage and 1,000 additional euros for moral damage.
"The municipality will not be impressed and continues its methodical work to contribute to good public order", reacted the LR mayor of Cannes David Lisnard.
