SAN ANTONIO (AP) -

Recruits at a South Texas Air Force base where more than two dozen instructors were convicted of sexual and other abuse are being asked if they've been mistreated.
    
So far no additional cases of alleged wrongdoing have been found at Joint Base San Antonio-Lackland.
    
Recruits in October began taking the voluntary, anonymous survey with dozens of questions about issues that include sexual harassment, sexual assault and attempts by instructors to flirt or have sexual relationships.
    
Col. J.D. Willis said early results show some recruits have concerns about bullying by fellow trainees.
    
The Air Force has tightened training rules since 26 instructors were convicted of rape, sexual assault, maltraining or having consensual but prohibited relationships. Male trainers mainly preyed on female recruits.
