Nevada: Balwinder Singh, 41, was sentenced to lifetime observation in US on Tuesday for his terrorist links back in India.

Singh, who lives in Northern Nevada has been jailed in December 2013. As he has ties with the terrorist groups in India for more than two decades and worked with two terrorist organizations Babbar Khalsa International and Khalistan Zindabad Force to try to establish an independent Sikh state in the Punjab region.

US District Judge Larry Hicks in Reno ordered Balwinder Singh to remain under lifetime federal supervision upon his release.

Defense attorney Michael Kennedy said Singh was beaten and tortured by Indian government officials in the past and never posed a threat to the United States. He argued any post-release supervision should be limited to five years. "It will be up to an (immigration) judge to decide whether to send someone back to a country where he has been tortured or whether we as a country still stand in opposition to those sort of things," Kennedy said after the sentencing.

He said if Singh will be extradited to India, he faces criminal charges in connection with a terror attack on a passenger bus that killed three people in India in April 2006.

Daniel Bogden, US attorney for Nevada, said Singh sought asylum in San Francisco using a false identity to elude Indian authorities and eventually obtained a permanent residence card in the US

"The terrorists groups engage in violent crimes in India to intimidate and compel the Indian government to create the state of Khalistan," Bogden told reporters. "These groups also target for assassination persons who are considered traitors of the Sikh religion and government officials who it considers responsible for atrocities against the Sikhs.”
