Several people were shot and around 22 were wounded in a brawl between Afghan and Eritrean migrants in Calais on February 1.
The fight reportedly started as migrants waited in line for food. A second brawl took place at an industrial estate a short time later.
Images circulating online showed large groups of men carrying clubs and sticks.
