French authorities have arrested an activist belonging to an ultra-left movement at a site belonging to national rail operator SNCF, days after sabotage attacks paralysed the network at the start of the Olympic Games, a police source said Monday.
The man was detained at Oissel in northern France on Sunday and had access keys to SNCF technical premises, tools and literature linked to the ultra-left, said the source, asking not to be named.
