James Henry O’Sullivan is accused of colluding with R Shanmugaratnam, a director of accounting firm Citadelle Corporate Services, to send a false document to a Dubai-based Wirecard subsidiary claiming Citadelle held more than $100 million in an escrow account.

O’Sullivan, 46, was arrested on Monday and is being detained pending further investigation. His case was heard by a court on Wednesday and adjourned until Sept. 8.

If found guilty, he could be jailed for up to 10 years, fined, or both.

The Briton’s lawyer did not immediately respond to a request for comment and Shanmugaratnam could not immediately be reached.

In July last year, Singapore authorities launched an investigation into Citadelle, Senjo Group and its subsidiaries after scrutinising Wirecard’s local operations.

Wirecard, founded in 1999, filed for insolvency in June last year, owing creditors almost $4 billion, after disclosing a 1.9 billion euro hole in its accounts, which auditor EY said was the result of a sophisticated global fraud.
