A Paris region town will impose an overnight curfew this weekend, after rioting triggered by the deadly police shooting of a local teenager.

The town of Clamart, which has about 54,000 people in the French capital’s south-west suburbs, announced the extraordinary measure on Thursday (local time) in a statement on its website.

It said the curfew would start at 9pm and last until 6am, from Thursday night until Monday.

It cited “the risk of new public order disturbances” for the decision, after two nights of urban unrest.

“Clamart is a safe and calm town, we are determined that it stay that way,” it said.

A police officer in a Paris suburb was handed a preliminary charge of voluntary homicide on Thursday after the deadly shooting of the 17-year-old that triggered two nights of riots.

The French government has vowed to restore order and crack down on violence that has spread to other cities.

Nanterre prosecutor Pascal Prache said his initial investigation led him to conclude “the conditions for the legal use of the weapon were not met” in the shooting.

The teen, identified only by his first name, Nahel, was killed during a traffic stop on Tuesday.

The shooting captured on video shocked the country and stirred up long-simmering tensions between police and young people in housing projects and other disadvantaged neighbourhoods.

Under French law, preliminary charges mean investigating judges have strong reason to suspect wrongdoing, but allow time for further investigation before a decision is made on whether to send the case to trial.

The police officer has been placed in provisional detention, according to the prosecutor’s office.

Ministers fanned out to areas scarred by the sudden flare-up of rioting, appealing for calm but also warning that the violence that injured scores of police and damaged nearly 100 public buildings wouldn’t be allowed to continue.

After a morning crisis meeting, Interior Minister Gerald Darmanin said the number of police officers deployed would more than quadruple, from 9000 to 40,000.

In the Paris region alone, the number of officers deployed would more than double to 5000.

“The professionals of disorder must go home,” Mr Darmanin said.

While there was no need yet to declare a state of emergency — a measure taken to quell weeks of rioting in 2005 — he added: “The state’s response will be extremely firm.”

Bus and rail services were shutting down at 9pm to safeguard transportation workers and passengers, a decision sure to impact untold thousands of travellers in the French capital and its suburbs.

“Our transports are not targets for thugs and vandals!” Valerie Pecresse, head of the Paris region tweeted.

Despite a beefed-up police presence on Wednesday, violence resumed after dusk with protesters shooting fireworks and hurling stones at police in Nanterre, who fired repeated volleys of tear gas.

As demonstrations spread to other towns, police and firefighters struggled to contain protesters and extinguish numerous blazes.

Schools, police stations, town halls and other public buildings were damaged from Toulouse in the south to Lille in the north, with most of the damage in the Paris suburbs, according to a spokesperson for the national police.

Fire damaged the town hall in the the Paris suburb of L’Ile-Saint-Denis, not far from the country’s national stadium and the headquarters of the Paris 2024 Olympics.

Mr Darmanin said 170 officers had been injured in the unrest but none of the injuries was life-threatening. At least 90 public buildings were vandalised.

The number of civilians injured was not immediately released.

Mr Prache, the Nanterre prosecutor, said officers tried to stop Nahel because he looked so young and was driving a Mercedes with Polish license plates in a bus lane.

He ran a red light to avoid being stopped but then got stuck in a traffic jam. Both officers involved said they drew their guns to prevent him from fleeing.

The officer who fired a single shot said he feared he and his colleague or someone else could be hit by the car, according to Mr Prache.

The officers said they felt “threatened” as the car drove off.
