i worked for a criminal lawyer for 8 years. If the police have not charged you immediately, the CPS will have been asked to look at the evidence against you to decide if they have a case (not if your guilty, but if they can prove you are guilty). You should have been given a date to return to the police station with your solicitor to find out the outcome (or you will be informed of one). The most a solicitor can do at this stage is to take a statement, but you've probably already given a statement to the police so they probably won't take one at this stage. Until the CPS decide what to do there isn't anything for the solicitor to do, so he isn't doing anything wrong, it's just there is nothing he can do until they decide.
When you return the police will either:
- arrest, charge you and bail you to attend court (less serious offences like careless driving); or
- if the charge is more serious (like rape, murder, attempted murder, robbery or basically anything that will carry a prison term including dangerous driving) they will arrest you and take you to the next available hearing (this could mean an overnight stay in a cell) for the court to decide if bail is appropriate.
If the police don't bail you and take you straight to the next available hearing at the magistrates, the solicitor will make a bail application on your behalf to the court. After this (whether you get bail or not) he will then prepare your case and present your case for you at the magistrates (less serious offences like careless driving) or, if it's serious enough to go to crown court (rape, murder, robbery, dangerous driving, he will instruct a barrister on your behalf (solicitors cannot attend crown court, it has to be a barrister).
that's basically what to expect. pm me if you're really worried but bear in mind i have limited internet access at the moment, but anyway at the moment there is not much else i can tell you, it's just a bit of a waiting game.
