Ryan Wells Or David Greiner Theft by Online Fraud London, UK London

I responded to a Motorcycle classified ad on http://www.motortraders.net/classifieds/item.asp?id=17629
A week later i received an e-mail from a Ryan Wells (ryan.wells@live.com)
He advised me that the Motorcycle I was interested in was still available and has been reduced down in price. He claimed he was in the military and that he was traveling at the moment and could not keep his bike, therefore was selling it cheaper then posted.
He gave me a site to register for the shipping arrangements http://www.idwarehouse-ltd.com/index.php
After I set up an account with the shipping company, the shipping coordinator
First name: David
Last name: Greiner
Address: 48 Albemarle Street
City: London
Zip: W1S 4JW
Country: United Kingdom
Gave me specific instructions on how to send funds (via Western Union) I had never sent Western Union so he explained the process to me. I at this point believed him since the shipping company was very real and seemed legit, I sent the funds.

At this point after verifying the transaction, I waited for the shipping company to verify received funds and processed the shipping. They verified the shipping information and said it would take 3-6 business days. I was given a tracking number to track the shipping as well as VIN# of the Bike. Again, very real and legit. After a week and a half goes by. I have kept in good contact with Ryan Wells; never would I have expected he was a thief. He was kind and responsive. A few more days go by and no word from seller (Ryan Wells) I notified BBB of situation and checked on shipping company, they mentioned they have never heard of this shipping company before.

I called the police.

Waiting for detective to call me back.

I have filed two reports with www.ic3.gov and no word yet.

Still no word from seller. Obviously no motorcycle yet.
Can someone help?
