What are police procedures in France when the victim is a traveler?

I have a friend who went to France a few days ago. Now I have received the following message from a friend of hers:
"Hello, I'm Amanda's friend (fictional name) and I received a call from where she is informing that she's at the hospital that she's injured at a hospital"
I asked for details…
"All I know is that she's physically injured, she also said you'd know what happened, they (the hospital staff) don't know what happened either"
And yes, I know what happened, but this is police matter (details removed)
Guy I suspect has already been arrested in my country and is sought by the police here, I want to find a way of informing the French police before he leaves the country.
I also don't know how to contact the French police or even find the hospital my friend is in, and I don't speak French.
I would also like to know what are the conditions in which the police may already be in the case.

It turns out it was a scam to garner money from me, what I wasn't expecting though was that my "friend" was the scammer.
- She was shaving her hair to tell people she had cancer
- She was mutilating herself to say she was agressed
- She took some drug to make her breasts make milk so she could say she got pregnant from rape
- She had proper dressing to hide her hernia (http://pedroaraujo.site.med.br/fmfiles/index.asp/::XPR1XB::/H%E9rnia_incisional.jpg) so she could show it only when convenient to justify a story of aggresion
- And so on
- Her family also supports her with houses and people to support her lies, acting as a gang.
- She very seldonly asked for money, she just kept doing it until u decided yourself to help her paying the hipothetical lawer and medicine (where in my case was around a month).
Because I don't want to have my name against a gang that knows where I live, I tried to make an anonymous delation on the police, but they simply answered they can't do anything without someone signing the delation and even if I did, it's highly unlikely that she'll be arrested because this is a "low dangerousness crime" and they won't give me police protection either.
By the way, I live in Brazil.
