Dorset Police has apologised after an independent enquiry into the murder of a woman by her former partner in Dorset found there were lost opportunities to prevent the tragedy.
Katrina O'Hara was stabbed to death at her salon in Blandford in January 2016.
Stuart Thomas, who was arrested days earlier for harassing her, was jailed for life for her murder.
The Independent Office for Police Conduct said taking her mobile phone as part of the investigation left her vulnerable.
Dorset Police has apologised and said it would continue to work to minimise the risks to domestic abuse victims.
Katrina's family said today their faith in policing had been shaken to the core and they hope her death will serve as a wake up call not to brush domestic violence under the carpet.
