The Trump administration moved Tuesday against Giovanni Vicente Mosquera Serrano, head of Tren de Aragua’s operations in Colombia, elevating him to the FBI’s “Most Wanted” list and slapping new financial sanctions on him.

And federal prosecutors announced a new indictment against Mr. Mosquera Serrano that accused him of drug trafficking and conspiring to support a terrorist organization.

The Venezuelan is the first TdA figure to make the FBI’s list, and the bureau called him “armed and dangerous.”

“Giovanni Vicente Mosquera Serrano’s leadership fuels an organization that thrives on brutal murders, forced prostitution, kidnappings, and the destruction of lives across continents,” said Douglas Williams, special agent in charge of the FBI’s Houston office, where the charges were brought.

The moves come as the Trump administration argues to federal courts that TdA, a gang formed in Venezuela but which has gone international, is a major security threat and its migrants here in the U.S. should be fast-tracked for deportation.

The administration has already declared TdA to be a foreign terrorist organization.

Authorities are offering a $3 million reward for information on Mr. Mosquera Serrano.

The FBI’s wanted poster for him gives his birthday as Feb. 22, 1988. It says he speaks Spanish and has black hair and brown eyes.

The current indictment against him, handed up in April and unsealed Tuesday, charges him with three counts of distributing cocaine and two counts of providing material support to TdA. Also charged with him is Jose Enrique Martinez Flores.
