Mexican authorities arrested Jesus Aurelio Ibarra Ramiro, aka “Commander Aurelio”supposed boss of the square Sinaloa Cartel and “Los Chapitos” in the Mexican northwest and in the Upper Gulf of California.

Although his arrest was revealed this Tuesday, his arrest took place on Monday at 4:50 p.m. local time, according to the National Detention Registry, at a safe house in the La Botella neighborhood of the town of Sonoyta, in the state of Sonora, border with Arizona, United States .

During a security operation to prevent his accomplices from trying to rescue him, agents from the Public Security Directorate of the State transferred “Commander Aurelio” to the facilities of the Office of the General Prosecutor (FGR) in the municipality of Plutarco Elías Calles . . The subject is accused of being one of the leaders of “Los Chapitos”, a faction led by the sons of Joaquín “El Chapo” Guzmán, ex-capo of the Sinaloa Cartel.

Mexico sends “El Chapo” Guzmán’s in-laws to prison, after he is deported from the United States: who is alias “El Señor”?

“Los Chapitos” are among the most wanted criminals in the United States, who in April announced charges against four of Guzmán’s children for trafficking fentanyl. Aurelio Ibarra is one of the suspected operators of the main cartel in the state of Sonora and is considered one of the main instigators of violence in the area.

The capture comes as pressure mounts from Washington against Mexican drug cartels trafficking fentanyl, a synthetic drug that the U.S. Drug Enforcement Administration (DEA) says is made in Mexico from chemical precursors from Asia.

In the Upper Gulf of California region where it operated, in addition to trafficking drugs, guns and undocumented migrants, organized crime groups also engage in the illegal trade of marine species such as the totoaba crop and the cannonball jellyfish, whose fishing began this Tuesday.

The latter species is considered the new business of criminal groups in the region, which they are trying to control their fish market to ensure the transfer of the species to Korea, Singapore, Japan, Vietnam and China, where there is a high demand for jellyfish or jellyfish for human consumption, the pharmaceutical and cosmetic industries.

In the last fishing season, between 80,000 and 100,000 tons of jellyfish were exported from the northwestern region of Mexico to Asian markets.
