A mother attacked with a hammer by her partner after reporting him for a previous attack was repeatedly let down by South Wales Police, the Independent Police Complaints Commission has said.
The force did not realise Christopher Veal was a convicted rapist because they mis-spelt his name.
Shortly after police left Charmaine Lewis's Cardiff home, Veal broke in and attacked her in front of her children.
The IPCC said one officer had a case to answer for misconduct.
Caroline Evans reports.
