Three police officers and one liquor control officer met Saturday night and paired as male-female couples, according to the report. They paid $30 each to enter, and approached a sign-in table for the "St. Louis Adult Connection" inside the club.

A man at the table identified only as "Todd" told them that the Connection used the venue every month from August through May, the report said.

"Anything goes here, but no means no," Todd told the officers, according to the report. "The sex is give and take; you get with someone's date, they can get with yours."

The officers kept a police lieutenant apprised of their work by cell phone, the report said.

Just before midnight, an announcement came over the speakers that police were entering the building. Patrons stopped the sex acts and swarmed the door, the report says.

The report does not say how many attended the party, but a liquor commission staffer estimated about 150.

City court summonses were issued to one patron for "Lewd and Indecent Conduct" and to Prohic for "Permitting Lewd or Indecent Conduct or Entertainment in a Licensed Liquor Establishment," according to the report.
