Shocking revelations have surfaced about Mexican cartels crossing the border and spying on American police officers and federal agents in an effort to murder their sources or informants. A leaked bulletin revealed that this deadly plot is happening near the border in Arizona.

The Arizona border is in the Tucson sector, one of nine border sectors on the U.S./Mexico border and is under the control of the Sinaloa cartel.

The revelations were first reported by a retired narcotics officer named Robert Arce working with Breitbart Texas.

According to the report:

This deadly plot is occurring in Douglas, Arizona, or surrounding areas by a special forces group of the Sinaloa Federation based out of Agua Prieta, Mexico. The cartel’s group, specifically a specialized surveillance team, is called “Grupo Delta.” The FBI-issued report names a specific individual as a known member of the Agua Prieta drug trafficking organization and it asserts that this individual deployed the cartel surveillance team into the U.S. for this effort. Breitbart Texas agreed to omit the name of the cartel operative in this report.

Though the FBI-issued situational report does not specify the name of the specific Mexico-based criminal group, Agua Prieta is controlled by a group known as Los Salazar which operates under the banner of the Sinaloa Federation; thereby making them part of the Sinaloa Cartel.

The report was based off of a leaked document sent out by the FBI to law enforcement partners. Big League Politics was able to confirm with a trusted source that the document and the allegations were accurate. The original Breitbart report can be read here.

Southern Arizona near the border has cartel scouts operating in the region, a fact that even mainstream media outlets acknowledge. A local Phoenix mainstream news team news team decided to challenge law enforcement claims of such scouts and the news team found out such spying was indeed occurring. AZFamily.com reported:

At this point in the story, it makes sense to switch to writing in first person, because the day after Detective Castro guided us through the smuggling hot spots, CBS 5 producer Gilbert Zermeno and I decide to hike up the side of one of the peaks above Hidden Valley to see if we can find evidence that the cartel scouts are really up there.

The side of the mountain is steep, with no trail to follow. We can see signs that others have been on this mountain. It makes sense because the range is so close to a neighborhood. But we do not see the tell-tale signs of illegal immigration or drug smuggling: garbage and clothing.

About halfway up the mountain, we decide that Gilbert will stop, film me from that spot, and I will continue to the top, using my cell phone video camera to capture what I see.

As I climb up the final rock escarpment and pull myself up over the ledge, I immediately realize that I’m no longer by myself. A lone man, sitting under a tree next to a cactus, dressed in camouflage, listening to a police scanner, holding a large bag of cell phones and extra batteries looks up at me, and his expression mixes fear, alarm, and hostility.
