MOSCOW, January 6 (RAPSI) – The U.S. District Court for the Southern District of New York on Tuesday refused to extend prison term for Latvian national Deniss Calovskis charged with involvement in the Gozi virus scam, Reuters reported.

Calovskis spent 21 months in prison before he pleaded guilty in September to conspiring to commit computer intrusion, according to the agency. Prosecutors filed a motion for additional time in custody for Calovskis. However, a judge ruled that the goal of his punishment has been already served.

According to David Bertan, lawyer for Calovskis, the sentence which also includes a fine of $1,000 could mean that his client could be returned to Latvia within weeks, Reuters reports.

Calovskis, 30, who resides in Riga, worked on the Gozi virus with Russian national Nikita Kuzmin and Romanian national Mihai Ionut Paunescu, according to the U.S. authorities.

US law enforcement officers arrested Kuzmin during a visit to California in 2010 and persuaded him to cooperate. He helped prosecutors nab the other two men who were arrested in 2012 in their home countries. Nikita Kuzmin and Romanian Mihai Ionut Paunescu are already in US custody.

Chalovskis spent 10 months in Latvian jail. In February 2015, he was extradited to the US and taken in custody for a term of 11 months.
