MUNICH/FRANKFURT—Wirecard’s former boss was arrested on Tuesday on suspicion of falsifying accounts, after the German payments firm disclosed a $2.1 billion financial hole and questioned whether trustees had actually held money on its behalf.
Markus Braun turned himself in to prosecutors in Munich on Monday after traveling from Vienna. A judge was due to rule later on whether to keep the 50-year-old Austrian in investigative custody or grant him bail.
