So, going for a pee means your gay and asking for it?I'd say it is because he's a gay boy that has panicked when he realised - and they got the blame for it. He wasn't frog-marched to the toilets - he was already on the way there. How did the men know where he was heading so that they could follow him? It's time for the police to ask some personal questions - his schoolmates too.
And why is your version of events different from all others published?
