The suspect may not an ID with them. Waiting until you identify the person is an extra opportunity for them to disappear. Naked mugshots can be a solution in some places. Some write that in Russia police can beat the confession out of you, keep you for a couple of weeks in jail until the visible wounds heal and then send you to court together with the confession you signed. Naked mugshots will not help in this specific situation, because the court is corrupt together with cops and they will just ignore the procedures. But if I had a choice, I'd prefer a naked mugshot to torture (and of course, they can torture you without leaving any traces; with electricity, for example).
