I guess now the only thing Mr RESLUCHUB you can do is wait for the reply from the HK police. The other thing that might help is to try look for other victim thru all airsoft forum that had bad experience with this seller, and possible have them send an e-mail to the HK police.
By the way, I kind of remember seeing the gear pics on the Europe systema forum. May be you can try there too...good luck,
