Your links are to the right story. I do recall there was a lot in the news at the time about SD's working practices and I seem to recall in one report that the mother was a migrant worker, possibly Eastern European and possibly not entirely legal either.
Usually, in cases where the parent has been arrested like this, there's some report at a later date on the outcome of the court case, even if it doesn't name the parties involved. There doesn't seem to be anything more, though. Wonder if there was a complete reporting embargo on the case for some reason.
I only remember the case, really, because we were staying not far away and it was the big story of the week locally.
