The UK’s Serious Fraud Office has approached Barclays with a deferred prosecution agreement as it looks to resolve a long-running probe into how the bank secured emergency funding from Middle Eastern investors during the financial crisis, according to a person familiar with the matter.

The SFO launched an investigation in 2012 into whether the bank breached disclosure obligations when raising billions of pounds from investors including Qatar Holdings in 2008. The SFO interviewed a series of former top Barclays executives as part of a years-long probe into the allegations, according to people familiar with the matter.
