Warwickshire’s police force had the lowest rate in the past year out of all the forces in England and Wales of rapes recorded against adults which resulted in charge or caution.
Recently published figures show that only six per cent of rapes handled by the constabulary in 2012-13 resulted in one of the two outcomes - compared to an average across the 42 forces in England and Wales of 18 per cent. The highest rate was recorded by Durham Police at 32 per cent.
The news comes as the Director of Public Prosecutions Alison Saunders announced last Friday that she was launching measures aimed at improving the conviction rate. The joint Crime Prosecution Service (CPS) and police action plan will include monitoring the quality of decisions when police forces decide to drop an investigation.
