NEW YORK (AP) - A second inmate at New York's Rikers Island may have suffered a gruesome death.

Documents obtained by The Associated Press show that in September, 39-year-old Bradley Ballard, a mentally ill inmate, was found naked and covered in feces, and a rubber band was tied around his badly infected genitals.

He had been locked alone in his cell for seven days.

Records say Ballard was checked on dozens of times before being rushed to a hospital.

Another mentally ill inmate died in a 101-degree cell in February.
