The Ghanaian native communicated via Facebook and “explicitly discussed the methods he uses to covertly transport narcotics,” wrote James Holt, a US Immigration and Customs Enforcement agent.

Last month, a high-ranking official in Malaysia said that international drug syndicates were using Facebook to recruit young Malaysian women as drug mules.
