As during a similar action on 2 January, the protesters were trying to stop the passage of lorries travelling to the Netherlands. The driver appears to have been trying to force his way through the blockade.
A traffic expert and a medical examiner were sent to the scene to determine exactly how the accident happened.
According to police the driver of the Dutch truck was not immediately held because of the atmosphere at the scene, but was ordered to stop at a car park further along the road where he could be interviewed and subjected to alcohol and drugs tests. However when police arrived, he had gone.
As a result of the accident, one whole side of the E25 was closed, and police installed a diversion.
The driver, according to magistrate Catherine Collignon, is being “actively sought” for questioning.
