The UK's Serious Fraud Office (SFO) has opened an investigation into Autonomy, according to HP, after it accussed the firm's former management, including chief executive Mike Lynch, of accounting irregularities.
The accusations first surfaced last year when HP announced it was taken a $5bn write down on the deal after it uncovered issues with book keeping.
Now, in a recent Q-10 filing HP confirmed that the SFO had begun its investigation.
"On 6 February, 2013, representatives of the UK Serious Fraud Office advised HP that they had also opened an investigation relating to Autonomy. HP is co-operating with the three investigating agencies," it said.
V3 contacted the SFO for statement but had received no reply at the time of publication.
Lynch was also contacted for comment but no reply was forthcoming.
Since the accusations were first made Lynch has been vocal in his frustration with the way HP has handled the situation, claiming he was never contacted before the claims were made public and that he has not had a chance to discuss the claims with anyone at HP.
The deal to purchase Autonomy has caused numerous headaches for HP's management and shareholders are currently in revolt over the deal, urging investors not to reappoint two directors or its auditors due to a string of bad acquisitions, including Palm and EDS.
