Forgive me for posting this again, but I think with all the bickering the info, which may be of use to some, will have been lost.
If you are the victim of a crime in Spain, it should be reported to the Policia Nacional or the Guardia Civil. (not the Local Police) OR, you can call 902 102 112 (available 24 hours a day every day) and give the details in any of several languages, including English. You can nominate any National Police Station where you would like to sign the actual report within 48 hours (until it is signed you have not made a 'denuncia' that's Spanish for a crime report) and you will be given a reference number, so the police can find the info on the police computer. It is not a crime report number. If you are able to ID the suspect you will be asked to look at photos.
Note. You cannot make a crime report to the police in the street / at the scene of a crime.
Having signed the Crime Report you will be given a copy. After any immediate action that is necessary has been taken, the report will go before a judge who will direct what further steps are to be taken.
Unfortunately you probably will not get to hear what is done unless further info is required, a person is arrested or your property is recovered. That does not mean that you cannot go to the police station, for the area where the crime occurred and ask for an up-date.
(I have been a volunteer interpreter with the police for 17 years. If you think I can answer any of your questions please ask.)
Added.
If you are not satisfied with the service you receive, remember, just like all other places, the police have complaints forms which you can ask for. I have done so on a couple of occasions for 'customers' and the police have gone to great lengths to satisfy them. Just like anywhere else, the police would rather satisfy you than have you make a complaint.
