Exposed: the bank trader blamed for £60m losses

Matthew Piper, 36, is facing allegations that he inflated trading profits in a vanity and wage-boosting exercise.

He works as a £150,000-a-year trader on a team of 12 at Morgan Stanley, which he joined in 2004, making complex financial bets on the stock market.

His team are considered the "geeks" of banking because of their ability to compute arcane mathematical equations.

But Mr Piper has been suspended and an internal investigation launched after a routine audit flagged up alleged profit exaggerations.

He was not at his £1million home in Spitalfields last night and his parents in Truro, Cornwall, are refusing to comment.

A picture of Mr Piper on his Facebook social networking page shows him walking his dachshund Valerie.

A woman who answered the door of his east London home broke down in tears and sobbed: "I don't know. I don't know where he is."
