PARIS -- Bottles of gasoline and “a rudimentary ignition device” were found this morning under trucks at a cement site in Paris, police in the French capital told ABC News.

Employees of the LafargeHolcim building materials company discovered the device and about half a dozen mineral water bottles filled with gasoline under three trucks belonging to the French-Swiss company. The site is located in Paris’ 19th arrondissement.

Nothing exploded, no one was injured, and no one has been arrested, according to police.

The Paris prosecutor’s office has opened a criminal investigation into the incident.

LafargeHolcim is under investigation for allegedly striking deals with ISIS extremists in Syria. It was unclear if today’s case was linked to that investigation.
