Met police officers wrongfully access and leak the identity of a protected witness

In 2017 two Metropolitan police officers were jailed for five years for hacking into the force's intelligence database and leaking the identity of a protected witness to the defence lawyer in a 2011 murder trial that eventually saw the defendant, Leon De St Aubin, convicted. While the trial was in progress, the St Aubin's girlfriend, Lydia Laura, got a job as a civilian custody officer at Hammersmith police station without disclosing her relationship. In return for sexual favours, police colleague Hayden Cheremeh helped her access the database.
