The Drug Enforcement Agency (DEA) arrested on Sunday dozens of undocumented migrants tied to Venezuelan-born gang Tren de Aragua following the raid of what authorities described as a "makeshift nightclub" in Adams County, Colorado. Several of them were taken into custody.

ICE Enforcement and Removal Operations detained the nearly 50 people, many of which are “connected with the Tren de Aragua (TdA) gang from Venezuela,” according to the DEA.

How many people arrested Sunday were connected to the TdA gang is unclear, but DEA officials said the number was in the dozens.

Federal agents interrupted a party at a "makeshift nightclub" north of Denver early Sunday morning and arrested almost 50 people of undetermined immigration status, a large number of whom are reportedly affiliated with the Venezuelan Tren de Aragua gang.

More details emerged Monday about a federal raid on a pop-up nightclub early Sunday morning near Denver, that was aimed at disrupting the operations of the Venezuelan Tren De Aragua gang in Colorado.

The Drug Enforcement Administration said in a press release that of the 49 people detained in the raid early Sunday morning, at least 41 were undocumented.
