Detainee alleged that U.S. forces captured him and took him to Dhyla Al Mokhadia Base, an Iraqi Civil Defense Corps location, where he was deprived of food and water for three days with his hands tied and eyes blindfolded.  He alleged that an English-speaking male and an Arabic-speaking male leaned him against a wall and  repeatedly beat his head and back during interrogations over the course of three days.  Upon transport to Abu Ghraib, a CID agent noticed scars on the detainee's back and asked him about them.  Three times, the detainee claimed they were from a car accident and not from any abuse.  Four days later, the detainee told the same CID agent (whom he claimed never to have seen before) that the marks were from abuse.  A medical exam indicated that the marks were not consistent with the type or time period of the alleged abuse--instead of 4-7 day-old kick marks, the medic found that they were partially-healed scratches and contusions from approximately 6 weeks prior.  The agent concluded that the detainee was fabricating the abuse allegation to obtain monetary compensation or early release.
