Tren de Aragua is a transnational criminal organization from Venezuela. Tren de Aragua is led by Héctor Rusthenford Guerrero Flores, alias "Niño Guerrero"; he was incarcerated in Tocorón prison, which functioned at the time as the organization's de facto headquarters. The gang has expanded throughout Latin America and the United States with the mass migration of Venezuelans fleeing the regime of President Nicolás Maduro. Combating the gang has become a priority for many nations where Tren de Aragua operates. Though Tocorón prison was taken over by Venezuelan security forces in 2023, the leadership escaped.
