A sergeant stationed at McConnell Air Force Base has been arrested on suspicion of exposing sex partners to HIV by having unprotected sex with people he met at "swinger" parties around Wichita.

The Air Force Office of Special Investigations said Friday the man has not been charged but was ordered into a military jail at the base. The 43-year-old airman was arrested Aug. 9 and faces a September military hearing.

A search warrant filed in U.S. District Court shows he is under investigation for assault related to the parties.

An affidavit filed in support of the search warrant says the sergeant attended 21 Wichita-area swinger events from January 2009 until July. It says he exposed "multiple" men and women to the HIV virus.

Messages left Friday with his military lawyer were not returned.
