MOSCOW (AP) — A Russian physicist convicted of spying for China has been released on parole and is continuing to protest his innocence.
Valentin Danilov was arrested in 2001 on charges of passing classified information on space technology to China. He claimed the information was already publicly available.
He was acquitted in a 2003 trial, but retried the next year and convicted and sentenced to 14 years.
After his release Saturday, Danilov told a news conference in the Siberian city of Krasnoyarsk that he would pursue his case with the European Court of Human Rights.
"Nobody still has told me what kind of secrets I have," Danilov said Saturday.
Danilov, who was a professor at Krasnoyarsk Technical University, was one of several Russian scholars and journalists prosecuted for alleged espionage by the Federal Security Service, the main KGB successor known under its Russian acronym FSB.
Rights advocates say the security agency has been emboldened in efforts to discourage Russians' unsupervised contacts with foreigners since Vladimir Putin, a former KGB officer and FSB head, became president.
