Tara, a Babbar Khalsa International militant had escaped from the high-security Burail prison in Chandigarh in 2004 and was absconding before being nabbed by Thai authorities on January 5 this year. Interpol had issued a Red Corner Notice on the request of CBI.
Official sources said the authorities have deported him to India.
According to CBI, Tara, 37, was directly involved in the assassination of Beant Singh as he had purchased the car which was used to kill the CM in the Chandigarh secretariat with a humam bomb exploding.
Beant Singh was assassinated in a bomb blast at the secretariat complex in Chandigarh on August 31, 1995 by Babbar Khalsa International terrorists. The blast had claimed the lives of 17 others including three commandos.
