A man was arrested after illegally carrying a gun into a train station in the southern French city of Nimes on Saturday.
Police say the man is not linked to the recent attacks in Barcelona.
The train station was evacuated at the time, but thinks quickly returned to normal and police officers returned to their regular posts.
According to a national police spokesman, the man was quickly found and arrested, but the man's name is not authorized to be released to the public.
A train station in the French city of Nimes, which is near the Spanish border, has been evacuated.
A national police official said the evacuation was prompted by reports of armed individuals in the Nimes train station. The officer, however, said no shots had been fired.
Authorities are working to determine whether the activity is in any way linked to Thursday's attacks around Barcelona.
So far, authorities have not reported any injuries.
According to social media accounts, law enforcement officers are still on the scene.
Several news outlets are reporting that one suspect has been arrested, while two others are still on the loose.
French authorities have ramped up security at the Spanish border because one of the suspects wanted in connection to the Barcelona attacks is still on the run.
