As a top Mexican police commander, Ivan Reyes Arzate was trusted for years with the most sensitive information surrounding U.S. investigations of dangerous cartel drug traffickers, from notorious Sinaloa cartel boss Joaquin “El Chapo” Guzman to the violent offshoot faction known as Beltran-Leyva.
But last fall, after secret details about a Chicago-based probe mysteriously wound up in the hands of the cartel, agents intercepted a stunning conversation between drug traffickers talking about meeting with a law enforcement officer named Ivan.
A 42-page criminal complaint unsealed in Chicago on Wednesday alleged that Reyes had leaked crucial information to several targets of the undercover probe, including the identity of an informant who later had to be evacuated from Mexico for his own safety.
The complaint alleged that during a personal meeting with cartel leader Arturo Beltran-Leyva in 2009, Reyes revealed the identity of another informant who had been “instrumental” in securing an indictment against the cartel’s bosses.
On Beltran-Leyva’s orders, cartel assassins later kidnapped, tortured and killed the informant, according to the complaint.
