If it’s sabotage, given her recent sabotage campaigns in Europe, Russia’s probably on the French law enforcement possible suspect list. However, as of this writing, French law enforcement hasn’t said anything about Russia.

I remember a few years back when, during concerns over Islamic terrorism, some guy in Germany tried bombing a bus with a soccer team. His goal was to try to make money on sports betting. Was not, I think, anyone’s first guess.

I expect that they’ll be putting a lot of resources on finding the responsible party, though.

EDIT: Stock market manipulation of the team’s share price, not sports betting.
