The Indian government says it's investigating possible money-laundering offences involving a Chennai-based power company that's alleged to have diverted money to the Isle of Man.
The Enforcement Directorate in New Delhi says the OPG group may have breached the country's Foreign Exchange Management Act.
Investigators spent two days searching offices and say OPG managers diverted money to the Isle of Man as well as other offshore jurisdictions.
They seized more than three-quarters of a million pounds in cash during their searches.
