French police have made significant progress in an investigation regarding a ticket fraud scheme involving the Louvre, the world's most-visited museum.

Authorities have arrested nine individuals who are believed to be connected to this extensive operation.

Reports suggest that the fraudulent activities may have resulted in a staggering loss of around $11.86 million in ticket sales for the museum.

This investigation highlights the ongoing challenges that major cultural institutions face in combating fraud, especially in an era where online ticketing has become increasingly prevalent.
