No he hasn't. He left Jersey and went to Poland.
thanks for your response. That's useful to know.I just phoned St Helier Police Station in Jersey and they said that he would only be arrested if he lands in Jersey. The UK mainland wouldn't know about his arrest warrant in Jersey and unless it was very serious like Murder. They said they wouldn't have the money to chase/arrest him in another country in order to proceed with a less serious case such as his. So I think he is probably ok to be in the UK.Also do you know if arrest warrants time-out (for want of a better phrase) at any point? It has been 8 years since the offense?Many thanks
