In the midst of D.C.’s current synthetic drug problem, the Metropolitan Police Department announced today that they’ve made an “unprecedented” seizure of synthetic drugs.

In a press conference this afternoon, MPD Chief Cathy Lanier announced that the Narcotics and Special Investigations Division recently seized 116 kilos of synthetic drugs, which has an estimated street value of $2.3 million—the largest single seizure of synthetic drugs the District has ever seen.

The seizure included more than 19,000 packets of “Bizarro,” which has been one of several brands of synthetic cannabinoids that’s led to hundreds of overdoses throughout the District this summer. “Bizarro” and other synthetic cannabinoids like “K2,” “Spice,” and “Scooby Snax” has been a suspected cause in several homicides and violent crimes in D.C. this summer.

MPD detectives and agents with Homeland Security and the Drug Enforcement Administration arrested 33-year-old Siraj Issa of D.C. and 41-year-old Yenework Abera of Alexandria, Va. at approximately 12:52 p.m. yesterday. They both have been charged with Possession with Intent to Distribute Synthetic Cannabinoids.

“The seizure of such a large amount of synthetic drugs is a relief to both the MPD and the community,” Lanier said in a statement. “The hard investigative work that our members pride themselves on has potentially saved countless lives and helped to stem the violence that goes hand in hand with the selling and consumption of illegal drugs.”
