El Salvador’s Cecot mega-prison was notorious long before the Trump administration’s recent decision to deport hundreds of alleged Venezuelan gang members there.

Tren de Aragua was originally a prison gang that Hector Guerrero Flores turned into a "transnational criminal organisation", according the US state department, which is offering a reward of $5m for information that could lead to his arrest. Guerrero Flores, 41, was in and out of Tocorón for more than a decade.

CARACAS, Venezuela (AP) — Debates over President Donald Trump’s hardline migration policies are focused on the Venezuelan gang Tren de Aragua, to some a ruthless transnational criminal organization and to others the pretext for an overhyped anti-migrant narrative.

Venezuela's government on Sunday blasted the U.S. implementation of a rarely used wartime law, rapidly blocked by a U.S. judge, to deport over 200 alleged members of Venezuelan gang Tren de Aragua to El Salvador.
