A Goldman Sachs Group Inc. computer programmer who quit last month was arrested and charged with stealing codes related to a high-speed trading program that he helped develop.
The programmer, Sergey Aleynikov, 39 years old, was arrested Friday by Federal Bureau of Investigation agents as he got off a plane at Newark Liberty International Airport. According to a complaint filed Saturday, Mr. Aleynikov downloaded 32 megabytes of data from Goldman's computer system with "the intent to convert that trade secret to the economic benefit of someone other than the owner."...
According to the FBI, Mr. Aleynikov got a job offer earlier this year at an unnamed Chicago firm that planned to triple the $400,000-a-year salary he was paid at Goldman. The unnamed company is "new" and "intended to engage in high-volume automated trading," the FBI said in the court filing. (more)
