USA (QHA) - A university student in the US city of San Diego has received $4.1m (£2.7m) from the US government after he was abandoned for more than four days in a prison cell, BBC news informs. The justice department's inspector is now investigating what happened. Daniel Chong was one of nine people detained in the raid in April 2012. Authorities determined that they would not pursue charges after questioning him, but he was forgotten in prison cell. Loosing 7 kg Daniel Chong said he drank his urine to stay alive, tried to carve a message to his mother on his arm and hallucinated. After rescue he spent five days in hospital recovering from dehydration, kidney failure, cramps and a perforated esophagus. Mr. Chong's lawyer said that as a result of the incident the Drug Enforcement Administration had introduced new policies for detention, including checking cells daily and installing cameras inside them. Now lucky economics student at the University of California says he plans to buy his parents a house.
