The British Serious Fraud Office is heading for a new legal battle against Barclays Bank, which granted a multi-billion dollar loan to Qatar in 2008. The SFO, which investigates serious money crimes and corruption, filed a request with the British Supreme Court on Monday for reorientation to renew the charges against Barclays.

A lower court had dismissed the charges earlier, but Barclays expected in a statement that its troubles will not stop and that the SFO will redirect the charges before the Supreme Court.

During the global financial crisis, Barclays managed to avoid the fate of British banks saved by the government, raising $11.8 billion from investors mostly from Qatar. Later, the bank provided Qatar with a $3 billion loan.

The bureau suspects that the bank has lent the amount of money to Qatar to buy shares in it, meaning that the financial institution has lent itself indirectly, which is contrary to British financial law.

Over five years of investigations, the office discovered the enormity of Barclays’ dealings with Qatar and interrogated about 45 people, some of them more than once.

The SFO has charged the former bank's president and several senior officials for fraud and corruption in a Qatari loan.
