https://www.bbc.co.uk/news/uk-england-manchester-55894319Greater Manchester Police is being sued by the family of a woman who was stabbed to death by her boyfriend after she had told them he was abusing her.
Natasha Wild, 23, was killed by Lloyd Brackenbury, 32, in Rochdale in November 2016.
She had kept a diary and told three officers she had been thrown across a room, sexually abused and slashed in the chest, the Mirror reports.
Court papers claim one officer described the diary as "nothing".
The force accepted a probe by the Independent Office for Police Conduct found their investigation "fell short of the standards expected" and was "deeply" sorry.
It said it had "taken action in respect of the learning identified".
A spokesman added: "We would like to reassure anyone who is suffering abuse of any kind from a partner, ex-partner or family member that we take reports of this nature seriously.
"Officers undergo continual training to recognise signs of distress and abuse, and we work closely with partners to offer specialist support to those who need it.
