UBS made the disclosures two days after London police

Kengeter, who joined UBS in 2008 to rebuild its fixed income unit after Long Feather earrings it racked up record losses during the credit crisis, is among top executives that may face pressure to step down after the loss exposed flaws in the bank’s risk controls.
