The female former graduate trainee at UBS who has accused the Swiss bank of seriously mishandling a rape allegation she made against one of its senior managers has reported her claims of sexual assault to the Metropolitan Police.

The news comes as it also emerges UBS did not contact the Financial Conduct Authority at any time during its six-month probe into the woman’s allegations, according to people familiar with the matter. This is despite FCA guidelines stipulating that companies should keep the regulator informed of ongoing internal “issues” regarding any potential sexual misconduct.
