Is there a supervision law on sex-offenders in Spain?

[Idan]

I'm making a research on rehabilitation & legal aspects of sex offenders over Europe.
Is there is a supervision law on sex-offenders that already served their sentence (with or without prison),
I'd like to have a reference to that law. preferably in English.

Thanks,

I repeat my question please, I believe the answer is commonly known by citizens of Spain:
Is there a law in Spain of supervision and monitoring on sex-offenders after they served their sentence?
I mean, not only registration, but also active monitoring by official supervisors within the community.
Similar law exists in U.S. and Australia, as demonstrated at :
