Hello my name is ***** ***** I will help you with this.
Could you please explain your situation a little more?
If its a common assault then they have 6 months to find and charge.
If its a more serious assault then there is no time limit on when they can charge.
However if they cant find the person, its up to the force when they close the case. It really depends on whether there are any leads or anything - if not, then sadly in reality the case may be closed.
I am sorry if this is not necessarily the answer you want and certainly not the one I want to give you, but I have a duty to be honest.
Can I clarify anything for you about this today please?
If this answers your question could I invite you to rate my answer before you go today, otherwise the site doesn’t pay me for the time spent with you. Thanks in advance and good luck.
