 The opposite of a public relations exercise, Thames Valley and the police in general came under sustained criticism when an episode of the programme showed three detectives interrogating and dismissing a rape victim.Shocked at the attitude and behaviour of his officers, and the public reaction, Imbert instigated improvements to the handling of rape cases to Thames Valley which were adopted throughout the country.Imbert returned to London in 1985 as Deputy Commissioner, becoming Commissioner in 1987.
