The counterfeit currency given by police to the kidnappers of a Seoul bakery owner has entered general circulation…
…serial numbers (EC1195348A)…
The imitation money was new denomination notes produced by the police in August 2007. The notes are of such quality as to be indistinguishable from genuine currency at first sight. But upon closer examination, their 1mm larger size and lack of hidden design work becomes apparent. However, because of their sophistication, Park initially had no idea that they were fakes. ’93I only found out that they were counterfeit because of the serial numbers,’94 he declared.Police are saying that the forged notes could circulate further.
