The Metropolitan Police and the Crown Prosecution Service have apologised to Liam Allan after the rape case against him collapsed.
The 22-year-old was cleared after lawyers discovered previously undisclosed text messages which cast doubt on the claim the sex was non-consensual.
The joint-review said: “There is no evidence that the phone download was withheld deliberately by the OIC (officer in the case) or CPS (Crown Prosecution Service) prosecutors.
“The disclosure problems in this case were caused by a combination of error, lack of challenge, and lack of knowledge.”
Commander Richard Smith said he and Claire Lindley, Chief Crown Prosecutor for London South, met with Mr Allan "where he received a personal apology from us both and I was really pleased to have that opportunity to meet with him face-to-face, allow him to read the report and apologise for the errors that were made.”
The Metropolitan Police are reviewing 600 cases of rape and sexual assault and thousands more are under review nationally, the CPS said.
Mr Smith said: "We have moved in 120 officers to assist with the review of the 600 cases we have which are post-charge at the moment."
Ms Lindley said: "The 600 cases live in the system presently are still being reviewed. That process has not yet finished."
"During the review some cases have given cause for concern. Some cases are discontinued in the normal course of events."
Although she could not give a figure on how many cases are involved in a national review of all rape cases, she said: "There must be thousands".
