Hello, I am a solicitor with 20 years experience. I will try to answer this for you.
By accepting a caution you have accepted that you used unlawful violence on the person concerned.
Th police can and will keep a record of it.
In terms of redress what harm have you suffered?
But you, having admitted using unlawful violence and causing an injury, will find it very hard to get any redress. There will be no compensation fro being verbally abused. Was the otehr party arrested? Do you know how they were dealt with by the police?
If you have been give a formal police caution you are required to sign a document in which you admit the offence? If this did not happen what do you mean by cautioned? Do you mean an officer said "You do not have to say anything etc.etc." to you.
Did you have a solicitor in the interview?
Were you arrested and questioned?
in that case yo have not been cautioned. If the police took your details they can keep t on the police national computer for intelligence purposes. This is not a criminal record. In terms of recompense I doubt if there is any form of compensation for the post accident incident.
I think there is nothing you can really do here except treat it as water under the bridge.
I would be grateful if you would please rate my answers as I will not get credited for answering you unless you do.
