Massive Arrests Made in Dark Web Fentanyl Operation

International law enforcement agencies have shut down an online marketplace on the dark web and arrested nearly 300 people who allegedly used it to buy and sell fentanyl and other opioids. The operation lasted for over 18 months and spanned three continents, resulting in the seizure of over $53 million in cash and virtual currencies, guns, and nearly 2,000 pounds of drugs. The sweep highlights the difficulty of stemming drug trafficking in the hidden corners of the internet.
