I imaging he will have been interviewed and bailed pending further investigation. if there's further evidence he'll be re interviewed if not the file will have gone to the c.p.s and theyll decide if there's enough evidence to charge or to release n.f.a. My guess Is that he'll be charged and put before the court for the possession of a class a drug but he'll be nfa'd for the sexual assault claims. Either way he's done here.
Even if it turns out he is totally innocent on all fronts, he still put himself in the position where he could be guilty. In many other walks of life the mere suspicion is enough to finish him, and this is no different.
