A report from the Independent Police Complaints Commission has found failings in the working practices of the Metropolitan Police's Sapphire sex crime unit between July 2008 & Sept 2009.
It found instances when officers failed to believe victims and in one example, a woman was pressured to drop a rape claim against a man who went on to murder his two children.
Deputy chairwoman of the IPCC Deborah Glass said it was a sorry chapter of the Sapphire Unit’s history.
"The pressure to meet targets as a measure of success, rather than focusing on the outcome for the victim, resulted in the police losing sight of what policing is about – protecting the public and deterring and detecting crime."
