Reuters is reporting that UBS trader Kweku Adoboli faced a new charge when he appeared in court in London on Thursday for a hearing on allegations that made an estimated $2.3 billion in unauthorized trades.

He has now also been charged with fraud dating between October 2008 and December 2010, relating to "reckless and inappropriate trades," Reuters reports.

Wearing a grey suit, the 31-year-old bowed to the public gallery when he entered a packed courtroom at the City of London magistrates court.

Adoboli acknowledged several acquaintances in the public gallery and spoke in a confident voice to confirm his name and address, but made no other statement.

Lawyer Patrick Gibbs said Adoboli was "sorry beyond words for what had happened." He did not enter a plea and was remanded in custody until a further hearing next month.Ā

Adoboli, the British-educated son of a retired United Nations official from Ghana, was arrested last week.

The case has prompted criticism of the bank's control mechanism and its business model embracing wealth management and investment banking.
