Inmates at a state prison in Alaska were stripped naked in front of female prison staff members, walked naked on a “dog leash” and left without clothing or cover in cold, filthy cells for hours at a time, according to a report released by a state watchdog.

The report, released online last week and referring to events from a 10-day period in August 2013, provided a look at how correctional officers at the maximum-security Spring Creek Correctional Center in Seward subjected prisoners to sexual embarrassment and harassment, as well as situations of extreme discomfort, seemingly as punishment for two incidents that had taken place earlier in the month.

The report, prompted by a complaint filed by an inmate, found that he and 11 other prisoners had been taken from their cells for reasons that were never officially explained, moved to a different location, unshackled and “ordered to strip naked in front of female staff.”

The complaint said the group was handcuffed again and walked nude on a “dog leash,” which the report identified as a cuff retainer, to another area of the prison while correctional officers ridiculed and laughed at them.
