A police officer mounted a vicious two-year campaign of harassment against a friend during which she falsely accused her of abusing her own child and having sex with a 14-year-old boy.

But rather than being subjected to disciplinary action Pc Kelly Jarvis was allowed to resign from Cleveland Police on health grounds, thereby safeguarding her pension rights.

Mrs Jarvis, 38, entered the false claims on her police force computer after falling out with her friend Fiona Miller.
