The arrests in El Cajon pulled in nearly 2 tons of marijuana and $630,000 in cash, along with explosives and high-powered weapons, law enforcement officials told the Los Angeles Times Thursday.
The suspects operated out of a social club that allegedly had links to Mexico's Sinaloa Cartel and an Iraqi organized crime syndicate in Detroit, investigators said.
The social club was a "hub of criminal activity conducted by Iraqi organized crime," said El Cajon Police Chief Pat Sprecco.
The Sinaloa Cartel, a powerful crime organization, provided the El Cajon traffickers with the marijuana, which was sold in Detroit for three times the purchase price, said Drug Enforcement Agency spokeswoman Eileen Zeidler.
"That's a typical drug-trafficking pattern," Zeidler told the Times.
The arrests followed a months-long investigation by local, state and federal officials. Investigators said the club has also been the center of a variety of other illegal activities, including car theft and gun smuggling.
The suspects caught in the crackdown, called "Operation Shadowbox," face a variety of charges, including conspiracy, distribution of narcotics and possession and distribution of automatic weapons.
