Police pepper-sprayed protesters in Paris tonight as suburban rioting spilled into the French capital.
Tension has gripped the Parisian suburbs since February 2, when a man called Theo was allegedly beaten up and raped.
Hundreds of rioters tonight took to the streets around the Barbès - Rochechouart station, close to Gare du Nord.
The areas is also close to the Sacre Coeur basilica in the Montmartre area, a tourist hotspot.
Windows were smashed, rubbish bins were set on fire and police cars targeted during the disturbance.

As fire crews went in to extinguish the blazes, lines of riot police were attacked and shops were looted.
A policeman at the scene said: 'Windows have been smashed and officers attacked. Small groups of protesters wearing hoods to hide their identities are causing trouble and then running away.
'Everything is being done to try and disperse the crowds, but this could go on for a long time yet.'
Tensions have been running high since February 2 when Theo, a youth worker, claimed he was raped by police with a truncheon, as well as racially abused, spat on and beaten around his genitals.
One officer has been charged with rape, and three more with assault since Theo was hospitalised.
He underwent emergency surgery and has since been visited by President Francois Hollande, who has appealed for calm.
There are fears violence could reach 2005 levels, where the death of two teenagers who were electrocuted while hiding from police in an electricity substation sparked weeks of riots and led to a state of emergency being declared.

The riots started at the beginning of the month over alleged police brutality in the arrest of a 22-year-old black man
The violence coincides with political tensions as the French presidential election campaign gains momentum.
National Front (FN) leader Marine Le Pen, widely expected to reach the decisive second round of the election, accuses the political 'establishment' of neglecting the suburban areas of Paris.
She said: 'All this is the result of complacency in French society, which is the fault of politicians who have governed us for years.'
A scandal engulfing one-time Thatcherite frontrunner François Fillon, over payments made to his family members, could give a boost to Ms Le Pen.
Small rallies have taken place in other French cities, including Rouen in the north, Nantes in the west and Toulouse in the south-west.
Around 50 people have been detained since the protests began.
