The DNA of a seven-month-old baby girl has been added to the police's national database designed to identify criminals. The disclosure reignited the row over the growth of Britain's DNA register, which is the biggest in the world. It was revealed this year that more than 100,000 DNA samples had been taken from children, aged ten to 16, who have never been charged or convicted of any crime. She is one of 47 children under ten whose DNA has been recorded and will be retained by the police until after their deaths. Source.
