Federal agents and local law enforcement executed "Operation Free MacArthur Park" on Wednesday, May 6, 2026, targeting an open-air drug market in Los Angeles known for fentanyl and methamphetamine sales. This joint effort resulted in at least 18 arrests and the seizure of over $10 million worth of fentanyl. The operation aimed to dismantle drug distribution networks, including those linked to the 18th Street gang and MS-13, which allegedly control territories within MacArthur Park. Investigators gathered evidence of numerous drug deals over six weeks, leading to a federal criminal complaint against 25 defendants, with some facing significant prison sentences if convicted.
