One of two Venezuelan nationals arrested by U.S. Border Patrol in Brunswick on March 30 was determined to be connected to the criminal gang Tren de Aragua (TdA), authorities announced on Friday. Earlier this year, the State Department designated TdA as a Foreign Terrorist Organization.

After the two Venezuelan citizens were detained in connection with a theft investigation, U.S. Border Patrol (USBP) became involved, the agency said. Both detainees had entered the United States illegally but then been released on their own recognizance, USBP determined.

“The days of catch and release are over, and violent criminals, gang members, and terrorists will be removed from this country,” Chief of the USBP Houlton Sector Juan G. Bernal said.

It was a resident agent who responded to the Brunswick arrest. The Resident Agent Program (RAP) allows an officer of the agency to live and work at an assigned location away from station, which aids responsiveness in a geographically large state like Maine.

On March 21, the Department of Homeland Security announced the arrests of 68 suspected TdA members in less than a week, then bringing the total number of arrests in the less than 100 days of the Trump administration to nearly 400. Brunswick’s recent apprehension of a suspected TdA member falls into this broader pattern.

President Donald Trump invoked the 1798 Alien Enemies Act on March 15 to respond to what he called an invasion of the U.S. by gang that emerged from Venezuelan prisons.

“TDA is one of the most violent and ruthless terrorist gangs on planet earth. They rape, maim and murder for sport. TDA is responsible for some of the most heinous crimes that have occurred on US soil in recent years, including the murders of Laken Riley and Jocelyn Nungaray,” the White House spokesperson said at the time.
