The famous Ritz hotel in Paris has been embroiled in a controversy over a missing diamond ring. 

The ring, worth over a million dollars, disappeared from a guest's room while she was out shopping. 

But security staff at the hotel got lucky, finally finding the ring in a vacuum cleaner bag after police got involved. 

Europe Correspondent Catherine Field told Mike Hosking that the discovery was a great coincidence. 

She says the ring was simply vacuumed up, according to the hotel.
