More than 100 people detained during a Sunday raid of an illegal Colorado Springs nightclub remain in U.S. Immigration and Customs Enforcement custody Tuesday.

ICE did not respond to requests for comment from The Denver Post, but an unidentified spokesperson told CBS Colorado that the number of detainees had dropped from 114 to 105. The agency did not explain why that number dropped or specify if those nine people had been released.

At least two other people were arrested by Colorado Springs officers during the raid, police department spokesperson Ira Cronin said.

Cronin said one was arrested on a warrant for failing to appear in Adams County Court and the other had a warrant out for their arrest for third-degree assault, criminal mischief and child abuse.

“The investigation into activity at the underground club is continuing, as we anticipate there will be more arrests made in the future tied to criminal activity at this location,” Cronin said.

The El Paso County Sheriff’s Office said deputies did not arrest anyone and were there to assist other agencies.

Local law enforcement received numerous 911 calls from people in the area about shootings outside the club, drug trafficking and overdoses during the months-long investigation leading up to the raid, said Jonathan Pullen, special agent in charge of the DEA’s Rocky Mountain Division, in a Monday evening interview with NewsNation.

Pullen called the club a “den of iniquity.” He said it had moved between multiple Colorado Springs addresses, but had been inside the building raided Sunday for several months.

The club was put on the DEA’s radar, and agents started conducting surveillance and undercover work when it entered the building at 296 S. Academy Blvd., he said. Immigrants from Guatemala, Cuba, El Salvador, Mexico, Venezuela, Colombia, Nicaragua, Chile and Honduras were all inside the nightclub when it was raided, Pullen said.

While agents reportedly saw members of the Tren de Aragua, MS-13 and Hell’s Angels gangs frequent the Colorado Springs club, it’s unclear whether any were inside during the Sunday operation, Pullen said.

The Department of the Army Criminal Investigation Division is working with the DEA to investigate the military members involved, but declined to release additional information Monday, citing the ongoing investigation.

Pullen told NewsNation that 17 military members were inside the club. It remains unclear how many were working security and how many were patrons.

At least some of the military members were stationed at Fort Carson south of Colorado Springs, an unidentified spokesperson for the Army base confirmed Tuesday.

“We acknowledge that there were some Fort Carson service members present at the location during the operation,” the spokesperson said in an emailed statement to The Post. “Each person involved in this incident is presumed innocent until proven guilty. We will look at everyone’s situation on a case-by-case basis.”

During military investigations, a service member’s conduct is judged against the Uniform Code of Military Justice, a set of rules that applies to all U.S. military branches and personnel. Violations of that code are considered crimes by military standards.
