I don't have any specific stories to offer, just a quote that jumped out at me from a recent NY Review of Books Article, "The Rape of American Prisoners". Here's what the National Prison Rape Elimination Commission found about female employees at juvenile detention centers:

Nearly 62 percent of all reported incidents of staff sexual misconduct involved female staff and male inmates. Female staff were involved in 48 percent of staff-on-inmate abuse in which the inmates were unwilling participants. The rates at which female staff seem to abuse male inmates, in jails and in juvenile detention, clearly warrant further study.
