Federal prosecutors objected to the smaller ankle monitor, arguing that the former head of investment banking for Goldman Sachs in Malaysia could become a greater flight risk. Lawyers for Roger Ng said the "cumbersome and heavy nature" of the GPS monitoring device, which constantly streamed Ng's location to authorities, made it uncomfortable for Ng to run, which is his preferred method of exercise. NEW YORK: A former Goldman Sachs banker charged in connection with a multibillion-dollar scandal at Malaysia's state investment fund 1MDB won a Brooklyn judge's permission to replace his ankle monitor with a smaller one so he can jog more comfortably.
