Mobile phone and some precious things were stolen from my friend, but the police refutes to start criminal case (proceedings) to investigate the crime. They are saying that the thief can not be detected. There is no lower limit on the amount of thief in our country (Baltic country, European Union), the crime obviously had been done, so - obviously the criminal case should be opened and investigation started. But police refutes to do this. Is there case law to appeal such decision?

My friend does not know IMEA code of this phone. But I have heared that police can request (during the investigation in open criminal case) the call history from the operator and IMEA code certainly is there. So - the remaining steps for solving crime are simple - locate the current location, e.g. in pawnshop and then request documentation who has made it a pawn. And the case is solved! So - can police refuse to investigate the crime that can be solved so simply?

The case happend in Baltic country but the practice from the any other EU country is welcome, especially from Germany as it belong to the continental law and the legal systems of the Baltic countries have borrowed a lot from the German law.
