A Tuesday news release says that Facebook's vice president for Latin America, Diego Dzodan, was arrested on an order from a judge in the northeastern state of Sergipe. Dzodan is accused of ignoring a judicial order in a secret investigation involving organized crime and drug trafficking.
The decision by Judge Marcel Montalvao follows the company's refusal to surrender user information from the WhatsApp messaging service, an application Facebook bought in 2014.
WhatsApp said in its own statement that it had "cooperated as much as we could given the architecture of our service." It said the company was "unable to provide information we do not have".
A separate judicial order forced Brazil's telecommunications companies in December to block WhatsApp over its refusal to cooperate with a police inquiry. The move snarled communications for many of its 100 million users in Brazil for around 12 hours. Facebook CEO Mark Zuckerberg at the time said he was "stunned" by the "extreme decision".
