If you are asking whether you can force them to charge then you cannot I'm afraid.
They will take your views into account when deciding what to do but that is only one factor to consider and the others would normally outweigh the views of a complainant.
If the injuries are minor and the defendant is otherwise suitable for a caution or a PND then the views of a complainant would not deter them I'm afraid.
There is no way this is going to lead to a charge on the facts you describe.
Can I clarify anything for you?
They will probably give him a caution.
We do not hae prosecution on demand in the UK so it really matters not whether you agree or not.
In terms of compensation, you can ask for the value of the damaged clothing minus the number of years you have had it. If he challenges it though you could have to produce the receipt or some other proof of purchase like a bank transfer. My own personal view would be that it isn't worth asking for compensation as it will probably be for a demeaning amount.
