A man drove a car into a group of people in northwestern France late on Wednesday, killing one and wounding 10 before being detained, multiple sources said.
The incident at around 10:15pm in the city of Caen was not thought to have a terrorist motive, the deputy prosecutor said.
It left seven people in a critical condition and three with minor injuries, according to local prefect David Claviere.
The ramming is thought to have occurred after a fight, a police source said, with Claviere saying the car "deliberately drove into pedestrians in the street opposite the train station".
The suspect, a 26-year-old man born in Russia, was not known to intelligence services but was known to the police "only for traffic offences", Claviere said.
