We have her actual street address and apartment number and we have given this to the police, but i can't go knocking on her door demanding information can i? and so we have to wait and see if the police question her. But really, unless she is already known to them as a thief or a fence, all they can ask is her is about her link to the guy in Moldova who just happens to be using a stolen laptop. It may just be an innocent skype call.(although i doubt that).
But if the police do nothing, we will think of something i am sure. A bit tricky really.
