CB was detained on the spot when he was caught in the act of exposing himself to children who raised the alarm.I wonder if it was procedural, if you mean the alleged masturbating or weeing in the park, reports say CB was arrested on the spot because there was a EAW in place, when were the children interviewed and was it a specialist interviewer, what we have learnt is that the German system does not video record the interviews.
It was after that the existence of the European Arrest Warrant was found to be outstanding.
At that time the EAW had absolutely no locus in offences against the children in the playground.
