Philippine investigators say they have identified dozens of people and entities of interest in their probe into Wirecard, and are focusing on two bank employees who may have facilitated a multinational accounting scandal at the insolvent German payments company.

Wirecard had claimed some $2.1bn in cash on its balance sheet had been transferred to accounts at two Philippine banks. Both banks—Banco de Oro and Bank of the Philippine Islands—denied the accounts existed, and officials say the money never entered the country’s financial system.
