Protesters - mostly young people - threw stones and iron bars near the main shopping mall in Bobigny, east of Paris, and police used tear gas to disperse several dozen people on Thursday.
The protesters were calling for justice after a 22-year-old man claimed he was sodomized with a police baton when he was arrested on February 2 in the suburb of Aulnay-sous-Bois. French media report the man was released from hospital on Thursday.
The reported sexual assault has prompted violent protests in several neighbourhoods with minority populations.
Four officers have been charged with rape and assault. Police deny the rape allegations.
