After six and a half years in prison, a man named Gao Yanlong received a compensation of 660,000 yuan ($101,904) for an unsubstantiated conviction, Beijing Times reported on Thursday. Gao said he will also petition a higher court for more compensation, explaining that the court officials didn't bow to him to express their apologies.

Gao was detained by police in Lingbao County, Henan province on charges of homicide on Jan. 21, 1992. He was then convicted of robbery and sentenced to death with reprieve by the Sanmenxia Intermediate People's Court. But Gao rejected that decision and appealed to the high court, claiming that he was tortured until he delivered a confession. Henan High People's Court later ordered a retrial, citing a lack of evidence for his conviction.

On Aug. 21, 1998, Gao was granted bail, but the case was never re-investigated in the following 18 years. Early this year, Gao applied for national compensation, and his charge was dropped due to insufficient evidence.

Based on the decision by the Sanmenxia Intermediate People's Court, Gao was compensated with 531,382.96 yuan for an imprisonment of 2,418 days. Added together with compensation for mental damages, the total compensation comes to 660,000 yuan.

Even so, Gao is angry that there was no official apology when his court decision was announced. The court explained that a formal apology was included in the decision published on their official website. Gao asked the court to publish an apology on provincial media.

Gao also wants additional compensation for his mental damages and financial losses, including the loss of his business, his family's living expenses, and his medical charges during imprisonment. Gao believes that his experience behind bars did him great mental and physical damage.

The total amount Gao is claiming is 2.03 million yuan, including 529,000 yuan for his time in custody, 500,000 yuan for the loss of his business, and 1 million yuan for mental damages.
