Law enforcement has seized more than 19 kilograms of fentanyl, 12 firearms, and more than $130,000 in cash over the course of the investigation.

A year-long wire-tap investigation led to an indictment by the U.S. Attorney’s Office Western District of Washington of 11 defendants on drug distribution and weapons charges. A 12th defendant with ties to the organization was indicted on illegal weapons possession in connection with a deadly shooting at a Hookah bar in South Seattle.

“This operation exemplifies the power of collaboration among law enforcement agencies at all levels,” said HSI Seattle Special Agent in Charge Robert Hammer. “By uniting our resources and expertise, we have successfully dismantled a criminal network that has endangered our communities through violent acts and the distribution of fentanyl. Together, we will continue to fight against violent crime and protect the lives of our citizens.”

Some 600 law enforcement officers from ten different agencies searched 31 locations. A total of 11 people were arrested: nine of those indicted and two additional defendants were arrested on criminal complaints.

Of these charges, two relate to guns he possessed on Aug. 20, 2023, at the time of a fatal shooting at a hookah bar in South Seattle in which he was injured and three others were killed. The final two charges relate to a firearm and ammunition he possessed on May 30, 2024. Ahmed is prohibited from possessing firearms due to a 2022 conviction for illegally possessing firearms.
