You are an idiot.I havent read all of this so forgive me if someone else has said this but in your post yo say that the lady informed you it was Jeff Abbott.... I don't think so because of 2 reasons
1)Sshe isn't allowed to tell you because of confidentiality, all anonymous tip off's are confidential and if she was indeed a chief inspector (from CID) then she would no that this was breaking her contract.
2) The Data Protection Act says you aren't allowed to give any personal information of any person(s) to any 3rd parties.
1) If it was an anonymous tip off, then Jeff wouldn't have given her his name would he? In many cases, you are allowed to know who has made a complaint against you. Who said she was a Chief Inspector (being the head of an entire Constabulary)? Also in order for something to be reported as "offensive", there has to be a person who has been offended. They cannot remain nameless. No body, no murder...if you see my point.
2) Data Protection Act, does not apply here in the sense that you are suggesting. His name is not personal information, it is a "tag" under which you could file personal information. His address and phone number, would be personal information.
