Drugs found at the Colorado Springs makeshift nightclub that was part of a large-scale federal operation Sunday morning are believed to have been supplied by the Mexican Sinaloa Drug Cartel.

The raid resulted in more than 100 migrants being taken into custody, and "several active-duty service members from local military installations" were also detained, the El Paso County Sheriff's Office said.

Family members and friends came to the scene in Colorado Springs to try to account for friends and family after the DEA, alongside various other federal and local law enforcement agencies, raided an "underground nightclub" over the weekend.
