Sir David Murray's company has called for police to investigate the leaking of information relating to the 'big tax case' concerning Rangers' finances.
Details of payments to staff and players were featured in a BBC Scotland documentary entitled Rangers - The Men Who Sold The Jerseys and a number of online outlets, including the anonymous Rangers Tax Case blog.
The BBC programme won a Scottish Bafta on Sunday, while the tax case blog was awarded the Orwell Prize for online political writing, but has since been taken down.
In a statement, Murray International Holdings (MIH) said the publication of personal information ws "disgraceful" and called for police to investigate how the BBC acquired it.
The company said: "In our statement released on 20 November 2012, we highlighted our concerns surrounding the volume of private and confidential information surrounding the EBT case that was made available for public consumption.
"This is particularly the case in relation to the significant quantity of personal financial data contained in the BBC Scotland programme broadcast on Wednesday, 23 May 2012 and set out in correspondence addressed to MIH in advance thereof.
"All individuals have an expectation of privacy in relation to correspondence and matters relating to their financial affairs.
"It is disgraceful that personal information relating to employees and former employees of MIH and its subsidiaries has been banded about in public in such a casual manner.
"There were only three potential sources of the complete set of documentation utilised in the broadcast and correspondence; being MIH's head office, the First Tier Tax Tribunal and HMRC, together with their respective advisers.
"Importantly, Rangers Football Club PLC did not have access to all of the material covered in the programme and letters.
"MIH's underlying concern is that there may have been criminal offences committed in connection with the provision of this material to the BBC.
"MIH therefore requests a formal independent police inquiry into how this documentation came into the possession of the BBC.
"In this regard, MIH will willingly and openly co-operate with any formal investigation, submitting itself to the same level of inquiry as any third party."
MIH was the majority shareholder in Rangers before Craig Whyte took over the club in May 2011.
HMRC declined to comment on the matter. BBC Scotland is aware of the statement but has yet to comment.
