Please REALLY need INFo asap !! fake fb?

A 13 year old used someone elses photos on fb but not name or anything and didnt harass anyone on the fake account just was bored. but then deleleted/decatviated the account and removed the photos?? Cos my friend did it, and I found out. and she asked me if i ever found who the photos belong to would i inbox them and i said i dno but say if i did, and they told the cops wot would they do btw this is in england thanks xxx
