Investigators believe the act was "deliberate... but apparently has no connection with a terrorist act," the public prosecutor's office in the town of Meaux said.

France has suffered a string of terror-related attacks, including the use of cars as weapons.

On August 9, six soldiers were injured after they were hit by a rented BMW in a western Paris suburb.

The suspect, a 36-year-old Algerian man, was later shot and wounded after a dramatic motorway chase.
