He's been missing in Cambodia for around 2.5 years now. 3 years this Oct, I think now. There has been a litttle bit of TV, radio coverage over here in the UK and local area where he lived. Also been on Sky News a few months back.
There are also many posters etc...In Embasy's and Airports in Thailand, Australia, Cambodia etc...

I believe there is now a $20,000 reward leading to his safe return.
I know its a long shot. But if anyone travels over there, keep an eye out.
Thanks.
