Waryam Singh was ordered to be released by Home Minister Rajnath Singh today.
He is currently lodged in Bareilly Central Jail in Uttar Pradesh.
The grounds cited by the Home Ministry for his release are good conduct as also consideration for the nearly 25 years he has already served in jail since his arrest in 1990 and subsequent conviction in 1995, official sources said tonight.
Singh has never availed of parole and his conduct in jail has been impeccable, sources said, adding that Uttar Pradesh government had moved a proposal saying he should be released as he is also 70 years of age.
