A police force which claimed it had arrested a nine-year-old boy for drink-driving has admitted a records mix-up.The 'schoolboy' was in fact a 19-year-old male but his date of birth had been inputted incorrectly on to the custody system.Cumbria Police released the information in response to a Freedom of Information request for details of under-18s arrested for car crime.However, the birth date error was repeated as the disclosure made national and local newspaper headlines.A spokeswoman for Cumbria Constabulary said: "The information used in this article came from a Freedom of Information request that was submitted to Cumbria Constabulary regarding the number of people under the age of 18 involved in vehicle-related crime."Unfortunately, the data provided by the constabulary about a nine-year-old drink-driver was incorrect. This error occurred because the male's date of birth was initially recorded on our custody system incorrectly, but this was later amended to his correct age of 19."We apologise for any inconvenience caused."Source: orange.com
