A man whose credit card was stolen and used to buy a winning lottery ticket is appealing for the thieves to come forward - so they can split the cash.
He asked his bank to block it but learned his card had already been used in a local shop, where two apparently homeless men had used it to buy a winning scratch card.
La Francaise des Jeux (FDJ), the state lottery operator, said no one had yet submitted the ticket to claim the prize.
The victim of the theft, identified in police documents as Jean-David E, had his backpack containing his bank card stolen from his car earlier this month.
Mr Debuisson said prosecutors may try to seize the winnings, considering them illegally obtained gains, and warned the ticket will eventually expire.
