The aircraft arrived Thursday at Piarco International Airport from the Bahamas for refueling before continuing onward to Libya through Cape Verde, according to the Airports Authority of Trinidad and Tobago.Immigration officials inspecting the aircraft found explosives onboard that had not been disclosed in accordance with international aviation and security procedures, the airport authority said in a statement.

Authorities detained the aircraft temporarily while conducting inquiries into the cargo documentation and security compliance. Officials later concluded that the crew and pilot bore no responsibility for the undeclared shipment.

“It was determined that no liability should be attributed to the pilot or crew,” the Airports Authority said, adding that the aircraft and personnel were subsequently authorized to leave Trinidad and Tobago.Officials did not specify the type or quantity of explosives being transported, nor did they disclose the aircraft’s ownership or final recipient in Libya.

Trinidad and Tobago, located off Venezuela’s northeastern coast, has long faced scrutiny from regional security agencies over narcotics trafficking and organized crime activity. The government has declared multiple states of emergency since 2021 in response to rising violent crime rates.

The incident comes amid heightened international monitoring of aviation cargo movements involving sensitive materials across conflict-linked transit routes.

Flores, a regional commander who controlled large portions of CJNG territory along Mexico’s Pacific coast, had been viewed by security analysts as a potential successor to cartel leader Nemesio Oseguera, known as “El Mencho,” following Oseguera’s death in a security operation in February.Garcia Harfuch said on social media platform X that Flores was detained under a Mexican arrest warrant and also faced criminal charges in the United States.

“He is also wanted by U.S. authorities for extradition. The U.S. government had offered a $5 million reward for his capture,” Garcia Harfuch wrote.The U.S. Treasury Department previously identified Flores as a “significant foreign narcotics trafficker” and said that a U.S. grand jury in 2021 charged him with conspiracy to distribute cocaine and heroin, among other offenses.

CJNG is one of Mexico’s most powerful and violent criminal organizations, with operations spanning drug trafficking, extortion and territorial control across several states. The cartel has long been a major target of both Mexican and U.S. authorities.

Carlos Olivo, a former U.S. Drug Enforcement Administration assistant special agent in charge and an expert on CJNG, said Flores’ arrest could have a deeper operational impact than the earlier killing of El Mencho.“He’s a significant figure,” Olivo said. “His arrest will have a bigger effect on CJNG operations than Mencho being taken out.”The detention is the latest development in a broader campaign against Mexico’s drug cartels under intensified federal security operations.

Garcia Harfuch has made the dismantling of CJNG leadership a priority and previously blamed El Mencho for a 2020 assassination attempt against him in which two of his bodyguards were killed.Security analysts had identified Flores as one of several senior regional commanders positioned to compete for control of the cartel after leadership disruptions earlier this year.

Mexico’s security environment remains under heightened international attention as the country prepares to co-host the FIFA World Cup this summer with the United States and Canada, placing additional pressure on authorities to demonstrate progress against organized crime and violence.
