He was released on Monday, but remains a suspect; however, there are no restrictions on him, and he can return to the UK, so from that I think it's looking good. They will later decide whether to prosecute him or drop the case. He had been due to appear in court on Tuesday, where the prosecutor could have asked him, under Dutch law, to be detained for a further 90 days. I seem to the feeling that under Dutch law that should it go to trial it's down to the defence to prove innocence - but I could be wrong
You are wrong. :-) If it goes to court, the prosecution still needs to prove that Van Persie is guilty beyond reasonable doubt. Otherwise, Van Persie is free to go.
Correct. And if new evidence arises, he can easily be detained again. Because the UK is in the European Union, an extradition procedure is not necessary.
They are detained the same way. Only the jail is a lot crappier than in Holland. The legal system is working in the same way as in the Netherlands, only in details it is different. Dutch judges and prosecutors are working in Curacao and Aruba. The father of one of the accused boys is one of these judges, and he was arrested too last week.
