On 24th April 2008, a police patrol is stoned at Fontaine-Mallet Estate in Villepinte, Greater Paris.
A police officer got a breeze-block in the face.
On 8th Mai 2008, two weeks later, in the same neighbourhood, Lamba Soukouna is attacked by the police. He is hit on the forhead with a butt of a flash-ball.
How can we explain this violence against Lamba?
