Officials in Paris have called adverts for a dating website linking students with rich men and women "shameful", and say they will work with police to remove them.
The RichmeetBeautiful website has been displaying a large mobile billboard across the French capital, encouraging students to get in touch with "sugar daddies" and "sugar mamas" to subsidise their studies.
It reads: "Romance, passion and no student loan, go out with a sugar daddy or sugar mama."
Gender equality minister Marlene Schiappa said she will look into whether the dating website - for people above 18 - is encouraging prostitution.
The website describes itself as a place where people can be "open and honest" in defining the conditions of their relationship.
