You may have a case against the police either for wrongful arrest or for something specific that happened during the arrest process. This is unlikely to be urgent, but you may want to start collecting evidence now.
Any statements that you write now may be able to be used as evidence in a claim or complaint later on. Injuries should be well documented.
Generally, you should wait until criminal procedures are over before thinking about claims/complaints.
There is a possibility that a complaint at this stage might encourage the police to charge. However if an officer committed an offence then this should be raised sooner rather than later, and there are time limits on certain claims. Contact a solicitor for advice on timing of complaints.
Get in touch with us as we may have useful evidence, and you may be able to make a joint claim with others.
