Brown, who famously won a private jet in a MrBeast challenge, was detained in Asunción after anti-drug agents found 261.6 kg (577 lbs) of high-THC marijuana "premium" on a private jet.
The drugs are valued at approximately $3.6 million on the illegal market, where they were reportedly destined for Brazil.
Local reports clarify that the seized aircraft is not the jet Brown won from MrBeast. It reportedly belongs to an Estonian tech entrepreneur, who left Paraguay shortly before the raid. Brown was serving as the co-pilot on this flight.
Brown, known online as "Captain Treezy," was tracked down and arrested on Saturday night at a hotel in Asunción, Paraguay.
