Gas tanks and documents in Arabic were in the past found in an unmarked car parked illegally next to Notre Dame Cathedral, sparking terror fears and at least four arrests, according to French reports.

A couple known to intelligence services as being “favourable to the ideas of Isil” were afterwards arrested on their way to Spain, after an anti-terror investigation was launched following the discovery of the suspicious vehicle containing up to seven cylinders on Sunday yards from the cathedral. A second couple was also later detained.
