At this stage the OFT was called in, along with investigators from the Serious Fraud Office. While the SFO later found there was insufficient evidence to support a case, the OFT was not so easily dissuaded.
In July 2005 it raided 22 firms across the East Midlands. This evidence-gathering exercise produced more information causing the OFT to widen its investigation significantly.
By summer 2007 some of the industry’s leading listed firms had confirmed to the City that they had been dragged into the investigation. The OFT started to make noises about record fines and rewards for whistleblowers coming forward with more information.

It is understood that all but nine are accused of cover-pricing - whereby a firm that does not have the resources to carry out a job it is tendering for contacts rival bidders to ensure its price will not win the job.
