Police in the southern French city of Nimes have arrested a man unlawfully carrying a pistol into a train station, but say he is not linked to the attacks in Barcelona.
After an evacuation and police operation at the train station on Saturday night, the historic city quickly returned to normal, with police returning to their posts.
A national police spokesman said the operation began when a passenger alerted police to a man with a weapon.
Police quickly found and arrested him, said the spokesman, who was not authorised to be publicly named.
The spokesman said the man has no apparent connection to Thursday's attacks around Barcelona, about 380km southwest of Nimes.
