The Philippines said Wednesday it will investigate links to the 1.9 billion-euro ($2.1-billion) Wirecard scandal, adding the European payment provider's ex-chief operating officer may be in the country.

The announcement follows the arrest in Germany on Monday of Wirecard's ex-chief executive Markus Braun on suspicion of fraud.

Prosecutors accuse him of false accounting and market manipulation in connection with the scandal, which is fast turning into one of Germany's biggest financial frauds.

They believe Braun artificially "inflated" the company's assets and revenues through fake transactions in order to make the company seem financially stronger and more attractive to investors and customers.

The assets were supposedly held in trust accounts at two Philippine banks to cover risks in trading carried out by third parties on Wirecard's behalf.

Philippine Justice Secretary Menardo Guevarra said Wednesday it wasn't certain Wirecard actually operated in the country.

The two agencies would also look into possible violations of the country's anti-money laundering law, Guevarra said.

The two Philippine banks allegedly involved -- BDO and BPI -- have denied having a relationship with Wirecard, while the central bank says the money never entered the country's financial system.

On Monday Wirecard admitted the money in the supposed accounts likely does not exist.

Asked if Wirecard's former chief operating officer Jan Marsalek would be among those to be investigated, Guevarra told AFP: "Yes, if we find him here."

Austria-born Marsalek visited the Philippines on March 3-5, Guevarra said, adding "there are some indications that he may have returned recently and may still be here".

Wirecard dismissed Marsalek on Monday.

"No arrest warrant has been issued against anyone. We've just commenced the fact-finding stage," Guevarra said.
