More than 300 law enforcement officers, both federal and local, were assisting Rocky Mountain Drug Enforcement Agency Operation early Sunday morning in Colorado Springs, Colorado.

According to the DEA, over 100 people in the country illegally were detained at what they say is an underground nightclub. Drugs and weapons were also seized.

The DEA says that in the nightclub, they found pink cocaine, evidence of prostitution, and multiple firearms. The DEA estimates there were around 200 people inside the nightclub at the time of the raid, including more than a dozen U.S. active-duty servicemembers.

Special Agent in Charge, Jonathan Pullen, with DEA Rocky Mountain Field Division said those servicemembers were either patrons or working as armed security guards at the underground nightclub. Pullen also said that the Army Criminal Investigation Division is working with DEA.

According to a crew on the scene, many different police cruisers, white vans, and armored vehicles were seen.
