Southwark Sapphire rape unit 'failed victims'

Police officers at a specialist rape unit in south London "encouraged" victims to withdraw their allegations in order to improve detection rates, the police watchdog has said.

An Independent Police Complaints Commission report said Southwark Sapphire squad's approach of "failing to believe victims" was "wholly inappropriate".

In one case four years ago a woman was persuaded to withdraw allegations against a man who later went on to kill his son and daughter.
