A statement from the Serious Fraud Office (SFO) relating to the accidental transfer of thousands of pages of evidence to the wrong person said:
The SFO has a duty to return material to those who supplied it, upon request, after the close of an investigation. In this instance the party requesting the return was sent additional material which had in fact been obtained from other sources.
The data constituted 3 per cent of the total data in the case. It consists of 32,000 document pages, 81 audio tapes and electronic media. Of this, 98 per cent of the material has been recovered and efforts continue to recover all the remaining material that has not already been destroyed by the recipient. No material relating to national security was included in the data.
