If you are considering suing the police your best course of action is to do this through a specialist solicitor to maximise your chance of success. Due to high levels of risk involved with suing the police many solicitors will avoid such cases, or only take them if the claimant is entitled to legal aid. The recent rule changes regarding this can make it very hard to get help this way, so you are now looking at a specialist solicitor who will take your case on a ‘no win no fee’ basis.
If you find a solicitor offering this service then your chances of success just went up as by taking your case on this basis they are effectively giving a vote of confidence in both you and your civil action. They know that by taking on your claim against the police they will be committing a much more significant amount of time and money than in an ordinary civil action. But to take it on in the first place they are confident that you will get the compensation you are entitled to.
A search on the Internet is probably your best bet for finding such a solicitor, unless you know of somebody who has launched a similar action and can recommend their legal advisor. Be prepared to be in it for the long haul as civil actions against the police are notoriously complex and can take years to reach their conclusion. With a specialist solicitor by your side however, you have a much better chance of success and you will only pay him if you are successful, so it’s worth sticking with it.
