Chennai Airport — about my lost wallet

I am mahesh krishnan, today[protected] i travelled from chennai to sydney via kulalampur through air asia. My flight was at 8.15 am, after my immigration clearance and customs clearance i went inside the flight. As soon as the flight took off i noticed that i lost my wallet which i had 500 canadian dollars and almost 1000 inr. Also i had some important visiting cards and other stuffs. It is a brown colour wallet. Kindly inform us in my email id [protected]@yahoo.co.in or [protected]@gmail.com. Or you can handover the same to my brother in law who lives in chennai his name is rajanbabu and he is available in [protected]. I am really stressed regarding this and i hope the airport authorities can help me out

Mahesh
