The Air Force Academy says another male cadet has been charged with aggravated sexual assault.
The school announced the charge Thursday but said it would not immediately release the cadet's name or any details of the alleged incident.
Jocelyn Stewart, a civilian attorney who says she represents the cadet, says he is innocent. Stewart also declined to identify him by name.
At least six cadets, all males, have been charged with sexual misconduct in the past 13 months. Charges against one were dismissed, one was convicted and a third is awaiting a court-martial.
Two others were awaiting decisions on whether they face trials.
The next step in the latest case will be a hearing for an investigating officer to decide whether to recommend a court-martial. The hearing hasn't been scheduled.
