Sounds like he was sent to Thailand with all this fake currency in December and it worked so well he extended his visa and finally his luck ran out. Shouldnt of got greedy.
Alot of Srilankan Tamils live in London and theyre up to their neck in fake passports ,currency and cheques. Thailand is the main clearing house because its big and busy not just lazy cops.Laos and Cambodia are too small and quiet.
