"WhatsApp cannot provide information we do not have," the company said in a statement. "We cooperated to the full extent of our ability in this case and while we respect the important job of law enforcement, we strongly disagree with its decision."
Facebook received a court order to hand over the data four months ago, which authorities said was related to a drug trafficking investigation. The Brazilian court ended up issuing the order three times, and it started to fine Facebook around $12,600 for not following through, CNN reports. That fine jumped to $253,000 a day last month, and on February 7 the court also issued a warrant for Dzodan.
His detention comes after Brazilian authorities shut down Whatsapp for two days back in December for reasons that still aren't clear. The messaging app has over 93 million users in Brazil, so it makes sense why Facebook would be hesitant to lose their trust.
"We're disappointed with the extreme and disproportionate measure of having a Facebook executive escorted to a police station in connection with a case involving WhatsApp, which operates separately from Facebook," a Facebook spokesperson said in a statement. "Facebook has always been and will be available to address any questions Brazilian authorities may have."
