I've tried ringing too, just rings out then voicemail. no replys to texts either.
I'm not saying that he is/has, but IMHO i think he's running.
thing is, most of us have his name(s), numbers, bank details, car reg etc
This should be enough to track him down wether personally or police
If people do go to the police however it might be a good idea to group together to do it, it may have more impact.
