A university student who was left in a holding cell for nearly five days without food or water is suing the United States Drug Enforcement Agency for $20-million. Daniel Chong, a student at the University of California San Diego, told NBC News that he drank his own urine and tried to commit suicide with a piece of glass. He says he was experiencing kidney failure and blurry vision when he was found. Chong was picked up at a party that was raided on April 20 where the DEA was looking for ecstasy pills. He was not charged and was supposed to be released directly after questioning.
