A peaceful demonstration over the alleged rape of a black youth by police in France has degenerated, with groups setting vehicles on fire.
Youths also threw projectiles at police in a Paris suburb, while the officers responded with tear gas.
Hundreds demonstrated by the courthouse in the north-east suburb of Bobigny on Saturday, calling for justice for the 22-year-old man arrested in Aulnay-Sous-Bois on February 2 during an ID check by four police officers.
The young man, who is still in hospital, says he was raped with a police baton.
The situation has sparked a week of nightly unrest in several small towns with minority populations.
One officer was charged with aggravated rape and three others with aggravated assault. All deny the allegations.
