Well, it all looks bad for him.
He had really better come out and give his side of the story,
and it had better be a really good story, because otherwise, all
the evidence points to this fella being truly guilty.
One can say that he was being framed, but his own tweets place
him at that restaurant having a late Sunday brunch yesterday. That
in itself is not ironclad evidence, but it does not make him look
any more innocent.
Also, it's one thing to have some unconfirmed rumours going
around, but to have Yahoo! Singapore pick up the story and confirm
it with the restaurant.... that's not good.
A little snooping reveals that all his dining partners can do is
keep mum or cry foul and say that it's 99% lies (and "based on a
single person's bad mouth").
