French anti-terror police have arrested at least eight people linked to a series of attacks on France’s high speed rail network.
Police say the eight are suspected of belonging to a far left political group, which has been under surveillance for several months.
The hunt for the saboteurs started after a number of overhead electric cables in the Paris region were snagged by metal bars.
The vandalism caused chaos over the weekend, with thousands of passengers en route to Britain, Belgium and across France suffering long delays.
In a separate incident on Sunday, a TGV train rammed two concrete blocks on rail lines near the French town of Narbonne, suffering light damage.
Authorities say the stunts appear to have been deliberately coordinated and could only have been done by those familiar with high tension power cables.
