A Stock Exchange announcement today said the “SFO no longer considered Sweett Group to be cooperating”.
Sweett is carrying-out its own internal investigation into the allegations first published in the Wall Street Journal last year of bribery claims in 2010.
The SFO launched its probe in July.
The Sweett statement said: “Sweett Group believes that it is doing all that it reasonably can to cooperate with the SFO investigation while at the same time exercising its fundamental right to legal professional privilege in fulfilling its corporate and regulatory requirements.
“In mid-August 2014, Sweett Group took the decision on legal advice to continue its independent investigation.
“Consequent to that decision, the SFO no longer considered Sweett Group to be cooperating.
“The Company will continue to comply with all reasonable requests made by the SFO, subject to legal professional privilege.”
