US military investigators conducting a probe into detainee abuse in Afghanistan and had told the International Red Cross on earlier occasions that he had been mistreated. Hicks told his family in a 2004 visit to Guantanamo Bay that he had been anally assaulted during interrogation by the US in Afghanistan while he was hooded and restrained. Hicks' father claimed; "He said he was anally penetrated a number of times, they put a bag over his head, he wasn't expecting it and didn't know what it was. It was quite brutal." In a Four Corners interview, Terry Hicks discussed these "allegations of physical and sexual abuse of his son by American soldiers". According to conversations with his father, Hicks said he had been abused by both Northern Alliance and US soldiers.

Hicks was a well-behaved detainee, but was in solitary confinement for 23 hours a day. The window in his cell was internal, facing onto a corridor.
