The nightclub had moved between several Colorado Springs addresses, but had been inside the building raided by federal agencies on Sunday for several months, officials said.

Officers from Immigration and Customs Enforcement are in the middle of processing people who were detained in a raid at what federal officials call an unlicensed nightclub in Colorado Springs over the weekend.

Federal agents raided a Colorado Springs nightclub, detaining over 100 people, mostly active-duty military personnel, but no criminal charges have been filed and the operation appears to have been focused on civil immigration enforcement.
