One more employee of Deutsche Bank AG will likely be subject to criminal investigation in Korea on suspicion of engaging in irregular stock trading, according to the Financial Supervisory Service.

FSS officials allege that an employee of Deutsche Bank rigged the price earnings ratio during his trading of an equity-linked securities product, which was issued by Korea Investment & Securities, in 2008.

The financial regulator is poised to request the prosecution to investigate the case by holding a panel discussion this week, an online news provider reported.

The sanction comes about a month after the prosecution indicted four employees of Deutsche Bank AG and Deutsche Securities Korea for manipulating stocks on the Korea Exchange last November.

In addition, the FSS is probing an employee of France-based BNP Paribas for similar practices. The case could also possibly be handed over to the prosecution.

There is a possibility that the Securities & Futures Commission, a decision-making body of the FSS, will fine-tune the regulatory sanction level on the two foreign brokerage employees this Wednesday.
