According to The Wall Street Journal, Adoboli confessed he had done the trades. Risk-control officers discovered the loss on Wednesday and began questioning Adoboli, who later left to go home. From there he sent an email to managers admitting he had done the trades. Adoboli was then arrested by the London police. In addition to the regular 24 hours, authorities have been granted a 12-hour extension for how long they can detain Adoboli. No charges have been made against the rogue trader.
