PARIS (REUTERS) - At least one person was killed and another injured after a car crashed into two bus shelters in the southern French city of Marseille, police said on Monday (Aug 21). The city's prosecutor said there were no signs to indicate that the incident was terrorism related.

The driver, a 35-year-old man, was arrested at the scene, the police source said. Police advised the public to avoid the Old Port area where the driver was arrested.

Marseille's prosecutor said there were "no signs" indicating that it was a terror attack, reported Le Monde. The man appeared to have sought treatment at a psychiatric clinic and investigators were leaning towards psychiatric disturbance as a cause of the incident, the official, who was not named by the newspaper, was quoted as saying.

The driver first hit a bus shelter around 8:15 a.m. (2:15pm Singapore time) in the 13th arrondissement - or district - in the poorer northern part of the city, before hitting a second bus shelter an hour later in the 11th arrondissement, several km south.

The incident comes as Spanish police hunt for the 22-year-old driver who ploughed a van into a crowd in Barcelona on Thursday.
