Paris protest rages over police violence

Protesters have burned cars and threatened police in a Paris suburb after allegations a young black man was raped by a police baton.

Police initially detained 26 people during the pre-dawn outburst on Tuesday in which a police car and other vehicles were set on fire in Aulnay-sous-Bois, a working class suburb northeast of Paris.

Authorities are wary of unrest in France's poor towns, remembering the fiery 2005 riots that spread through France - beginning in the Paris suburb of Clichy-Sous-Bois and then through social housing around the country.

The latest violence was a show of outrage in support of a young black man who authorities allege was sodomised with a police officer's baton last week during a spate of identity checks as part of a police operation targeting drug traffickers.

One officer has been aggravated rape and three others with aggravated assault.
