Under the Crime and Disorder Act 1998 section 115 the Police are able to disclose information with a 'relevant authority' "where the disclosure is necessary or expedient for the purposes of any provision of the Act" (a very wide ambit). The Housing Act 2004 made registered providers 'relevant authorities'. Therefore the Police can share information with social landlords where this can help solve or prevent crime and disorder. As social landlords have so many powers to tackle behaviour of this sort then it would be relevant and lawful to share information of this sort. I think some posters here are making assumptions about what the victim knew or wanted, which none of us can do at this stage.
