Checks on the bank accounts of the suspects already in remand custody, the NGOs connected to them and their friends have shown that money had been credited to the accounts in big amounts from time to time.
The fraud could be something that has gone beyond a hacking into a bank data, the senior police official said.
Several websites have reported that top government figures had received commissions from gas importations for Litro Gas company and that serious irregularities had taken place in those deals.
Until yesterday (11), the chairman of the company was Shalila Munasinghe, the second suspect under custody.
He is a citizen of England and had opened an account in a local bank by producing an identity card issued in the 1990s, which is illegible, the CID told courts yesterday.
Also, the first suspect, J.C. Nammuni, is a dual citizenship holder.
