Three bankers have accused a firm involved in private investigation of libel.
Anthony James, Alistair McLeod and Cliff Giddings allege that Hibis Europe wrongly suggested they had been involved in a scam that precipitated the collapse of a lender, the Financial Times reports.
The company suggested that the trio had "systematically perpetrated a criminal fraud on a giant scale".
As a result of the claims, the three British executives have been banned from leaving Bahrain.
In court documents filed by the men, it is said the report - which was distributed by Hibis to a law firm and an accounting company in London - accused them of conducting fraudulent transactions worth approximately £1.4 billion.
A filing by a legal representative for Hibis - which aims to help businesses manage fraud risks and conducts investigations into such illegal behaviour - revealed it intends to fight the suggestions made against it.
