A French police officer has been placed under formal investigation over a fatal shooting in Nantes, which triggered three nights of rioting, reports the BBC.
The officer initially said he had opened fire on the 22-year-old man in self-defence during a traffic stop in the Breil neighbourhood on Tuesday.
But his lawyer told AFP news agency that after questioning, the officer said he had fired by accident.
The incident led to violent clashes between groups of youths and police.
The trouble began on Tuesday after the man, named locally as Aboubakar Fofana, was stopped by police in his car. Police initially said he had refused to comply with orders and tried to reverse into an officer. Another officer then opened fire, hitting the man in the neck.
Officials said the man had been under surveillance for suspected drug-trafficking.
That night rioters burned cars and threw petrol bombs at the police who responded with tear gas. The violence continued on Wednesday and Thursday with buildings including a library, a shopping centre and schools set alight.
