Poor Guy
MellyMoo, the crew members name wasn't "leaked". It has now publicly been released in the press (refer to the Melbourne Herald Sun link above or TheAge.com). As the guy has been arrested by the UK police and isn't a minor it is perfectly legal to release the name. A suspects name is only withheld if they are a minor i.e less that 18yrs old.
According to the report he was refused bail and has been remanded (I guess people will be heading to accom as room available at 21st!!!)
However, all aside Terrier Two has a point. Before we turn on him too much it may be worth considering the possibility that he was ill or affected in some way. People under severe stress, depression etc can do weird things. I really hope thats the case and he didn't do it just for a lark or whatever. If so, he has really caused himself some problems as Melly points out.
