An Oxford University student has become the latest accused rapist to have his case dropped against him after two years on bail amid wider public concern about the actions of police and prosecutors.

Oliver Mears, 19, was told he was to be found not guilty following a review of evidence just days before he was due to go on trial.

The Crown Prosecution Service said it decided to offer no evidence against Mr Mears after reviewing evidence handed to them by Surrey Police, some of which was only received last week. A police spokeswoman told the Times prosecutors decided to discontinue the trial “for a number of reasons”.

It comes at a time where the Metropolitan Police has ordered a review of all its investigations into rape and serious sexual assault following the collapsed trials of Liam Allan, 22, and Isaac Itiary, 25. A third case against Samson Makele, 28, was also halted at Snaresbrook Crown Court on Monday after his defence team unearthed key images from his mobile phone which had not previously been made available, law firm Hodge Jones and Allen said.

Chemistry student Mr Mears, of Horley, Surrey, was arrested weeks after his 17th birthday and accused of raping and indecently assaulting a woman in July 2015. He was charged last June. He reportedly left St Hugh’s College because of stress.
