Sworn statement, interviewee stated, I was asked to observe an interrogation which possibly fell on the border line [of inappropriate techniques]. Also, stated that he/she "heard of an unauthorized interrogation by three interrogators in SEP 03. The interrogators took a female detainee at night and became fresh with her." Also, stated: "Ghost detainees were those detainees who arrived at Abu Ghraib, but did not possess all documentation necessary for full in-processing. They were usually sourced from TF-121 or Other Governmental Agencies."
