RIO DE JANEIRO (AP) — Police in Sao Paulo say they have arrested the vice president of Facebook in Latin America.

A Tuesday news release says Argentine Diego Dzoran was arrested on an order from a judge in the northeastern state of Sergipe. Dzoran is accused of ignoring a judicial order in a secret investigation involving organized crime and drug trafficking.

A Brazilian judge in December blocked the popular WhatsApp messaging service owned by Facebook because it refused to give user information to police.

Brazilians are among the world's most voracious users of social media such as Facebook, WhatsApp and Twitter. Around half of the country's population uses WhatsApp.
