Reports in France claim several people are being held in Paris after police found a car containing gas cylinders near Notre Dame cathedral, sparking fears of a new terrorist plot.
An investigation has been launched as the vehicle contained seven gas canisters and was just yards from the cathedral when it was found on Sunday. The area was cordoned off.
Notre Dame was one of Paris' famous landmarks and attracts thousands of tourists daily.
Reports claims there were no explosives or detonators on the Peugeot 607, which had no number plates. Some have also suggested there was a book written in Arabic inside the car.
Fears have risen as some think the car may have been set up as a car bomb.
Two people were arrested, who are believed to be a couple according to initial reports. But six people are now being held, according to Le Parisien.
