Nicola Horlick, CEO of manager of managers Bramdean Asset Management and one of London's highest profile money managers, was attacked Monday night outside her South Kensington home by muggers, one of whom hit her with a gun. Nothing was taken and the muggers fled on a mo-ped, according to police. Ms. Horlick, who was hit over the head and suffered a bleeding ear, refused to go to hospital and was at work today as usual, according to a company spokeswoman. London's Metropolitan police also are investigating two robberies that occurred in the affluent suburb around the same time. They believe the three incidents are linked, according to a police statement.
