Justice ministry officials are assessing whether environmental organisation Greenpeace put public safety at risk with an anti-nuclear train transport stunt, news agency ANP reports.

Last week, a Greenpeace activist was arrested after he and three others dug a shallow hole under the railway tracks. The hole was to have held a coffin which would have been part of a protest against a nuclear waste shipment to France.
The Telegraaf reported on the incident on Thursday, accusing Greenpeace of putting the country at risk of a nuclear accident.
Coffin
The organisation told a news conference held in response to the paper’s claims that the action was a harmless stunt. The aim was to place a metre-long, 30cm deep ‘coffin’ between the tracks. The coffin would have held a large balloon bearing the radioactive logo which would have inflated as the train approached.
Other activists would have warned the driver but even if he had hit the balloon, there would have been no danger to anyone, Greenpeace said.
The Greenpeace worker was released on Tuesday evening following a court order.
