MOSCOW, August 16 - RAPSI. The hearing at a New-York court in the case of former Goldman Sachs programmer, Sergey Aleynikov, has been set for October 23.

Last week, the prosecutor's office requested an arrest warrant for Aleynikov having charged him with the unlawful use of proprietary scientific material and copying computer related material.

Aleynikov's attorney, Kevin Marin, told Reuters that his defendant will try to prove his innocence.

On March 18, 2011, the U.S. District Court for the Southern District of New York sentenced the programmer, who was born in Russia but later obtained U.S. citizenship, to just over eight years in prison for stealing and transferring Goldman Sachs trading system source codes. Aleynikov's defense attorney then filed an appealed. In February, the programmer was released.

According to the U.S. Department of Justice, Aleynikov worked at Goldman Sachs as a programmer for over two years. He was responsible for developing computer programs and supporting the bank's trading system.

Prosecutors claim that in 2009, Aleynikov resigned from Goldman Sachs to accept a job at Chicago-based trading firm Teza, where he would be responsible for the creation of another high-traffic trading computer program built to compete with that of Goldman Sachs. Aleynikov allegedly took more than 3,600 lines of source code from the Goldman Sachs program on his last day with the firm.

He was arrested in August 2009 at Newark airport.

If found guilty, Aleynikov could be sentenced to four years in prison.
