SHANGHAI (AP) — An Associated Press investigation found widespread fraud in China's murky anti-counterfeiting investigations industry. [...] investigators do their best to "find" as many fakes as possible, doctoring documents and colluding with factories to make counterfeit goods they can "seize" for their Western bosses. In five instances, Western firms paid investigators who doubled as counterfeiters, manufacturing or selling counterfeit goods on the side, the AP found. The Associated Press found cases of investigative fraud involving counterfeit auto parts, medicine, personal care products and electrical components. A Chinese investigator with a primary school education defrauded one of the world's biggest consumer goods companies, opening four factories to pump out counterfeit goods he could "seize" and present for payment.
