<text>  A report into the death of Joe Lawton, 17, who killed himself after being arrested for drink driving, has confirmed failings at the station where he was held . A report into the death of an A-grade student who killed himself days after being arrested for drink driving found evidence of a concerning culture at the police station where he was held. Joe Lawton, 17, shot himself dead at his parents 850,000 home in Disley, Stockport, two days after being held at Cheadle Heath police station for drink driving. During an inquest into his death, lawyers for his parents claimed that police had mocked him for his middle class upbringing and his new car, contributing to his death. Now an Independent Police Complaints Commission report into Mr Lawtons death, made public for the first time, confirms there were failings at Cheadle Heath police station where the teen was held. The IPCC probe, which was kept hidden from the teens inquest but has been revealed by the Manchester Evening News, uncovered evidence of a concerning culture at Cheadle Heath. Following the report one Greater Manchester Police sergeant was moved from custody duty due to inappropriate behaviour, while another was given management advice, the report says. Two custody detention officers were also subjected to sanctions as a result of the investigation, according to a copy of the IPCC report obtained by the Manchester Evening News. Mr Lawton was stopped by police in Hazel Grove in August 2012 while driving his new Peugeot 207 home from a party, just weeks after passing his test. A breathalyzer showed he was over the drink drive limit and he was arrested. Lawyers for Mr Lawtons parents Nick and Jane pictured told an inquest their son was bullied for his middle class upbringing. The report, revealed today, found evidence of a concerning culture among police . The teen, who had recently gained one A and four Bs in his AS-Levels and was working on his university application and travel plans, was then held for seven hours overnight. But due to an anomaly in custody laws meaning 17-year-olds are treated as adults, Mr Lawtons parents Nick and Jane were not informed of the arrest after he opted not to tell them. Two days later he was found dead at home by his father. Next to the body was the police charge sheet, and a note saying he thought he had ruined his life. His parents have since led a successful campaign to have the age limit raised to 18, after an inquest was told Mr Lawtons suicide could very likely have been avoided if they were informed. The IPCC report, together with a response from Greater Manchester Police, were prepared in time for the inquest but were not submitted as evidence, meaning this is the first time they have been made public. Nick and Jane Lawton said the inquest was turned into a gruelling and frustrating process by the polices failure to reveal the reports. In a statement, they hit out at the behaviour and attitude of the custody officers, adding: We love Joe and will continue to miss him every day for the rest of our lives. Mr Lawtons parents were not informed that their son had been arrested in August 2012 due to an anomaly in custody laws. Parents Nick and Jane pictured have since successfully campaign to have the law changed . The IPCC said the force has said it has learned lessons and had been improving working practice. Assistant Chief Constable Garry Shewan, who gave evidence at the inquest, said: Our thoughts continue to be with the family of Joseph Lawton, and we sympathise with the issues they have raised following this tragedy. When Joseph died in 2012 there was a confusing anomaly where the Police and Criminal Evidence act led the police to treat 17-year-olds as adults, whilst the Childrens Act stated that 17-year-olds should be treated as children. Following the case and a judicial review in 2013 the government have changed the legislation relating to 17-year-olds in custody. The new legislation states that when a 17-year-old is arrested they are now treated as children for the purposes of informing people about the childs detention. While in custody Joseph made the decision that he did not want anyone to be informed of his arrest. However, if this happened today we would have informed his parents.
