The Serious Fraud Office has begun an investigation into Capital + Merchant Finance which was put into receivership in November 2007.
The investigation comes after the SFO was contacted by the receivers.
SFO Chief Executive, Adam Feeley, says the investigation is focusing on specific transactions with contrived structures and questionable supporting documentation which appear to have benefited some people.
He says the investigation is in its early stages and they have yet to speak with people involved, including those who may have benefited.
