Hello I am solicitor with 20 years experience. I will try to answer this.
I am not sure what you are asking here. Can you tell me what offence you are suspected of please?
Ok did you have a solicitor at the interview. Am I right in thinking that you are on police bail to return to the police station at some point in the future.
Was this an interview under caution? ie t the start did they say "you do not have to say anything but it may harm your defence etc.
If you were not arrested and are not on bail to go back then it may well be that the evidence against you is not strong. If yo have witnesses to the fact that you were somewhere else at the tie of the offence it may be worth contacting them to jog their memories so that they will remember it later if needed. Get something in writing and signed if possible. Apart from this there is probably nothing you can usefully do. I i snot a goo idea to chase the police officer to find out what is going on. It may not be easy fro you to do but the best thing to do is nothing as far as the police are concerned. Let sleeping dogs lie and hope you never hear of it again. The more time that goes by the less likely you are to hear about it again.
Getting work cctv is probably an attempt to check your alibi, but if it isn't retained as far back as necessary it is unlikely to be helpful.
Were you arrested because your fingerprints were found on he cd cover in the car in question?
Why did they connect you to that insert cover?
That doesn't prove you were in the car, this is a portable item that you may have touched when it was not in the car. If they want to i/v you again you should have a solicitor present. You will be entitled to a free solicitor of your choice or the duty solicitor.
The case against you does not sound strong. You simply have to wait and see what happens there is nothing you can do. My hunch is that it won't go anywhere but if you need to go back to the police station get a solicitor.
