from telegraph: Civil liberties campaigners and MPs have raised doubts about the national DNA database after the Home Office confirmed it contained more than 500,000 false or wrongly recorded names.
Suspects arrested over any imprisonable offence, including rape and murder, can have their DNA held even if they are not charged or are acquitted.
The database, the biggest in the world, contains about four million names.
But it has been dogged by problems. Statistics released by the Home Office show it contains around 550,000 files with wrong or misspelt names.
Lynne Featherstone, a Liberal Democrat frontbencher, told The Daily Telegraph that she wanted a full parliamentary inquiry into the "shocking" number of errors.
"What lies behind these statistics? Is it the police just accept the 'say-so' of those whose DNA they are taking and don't check their names and addresses?" she said.
"While the use of DNA can obviously be vital in solving crimes, anything that raises questions about the credibility of the base is not acceptable."
