The BJP MP further stated that the arrest of Narayanan had "terrorized the entire ISRO community."
"Regretfully, this is not just a case of a person being falsely accused in a case as stated by the Supreme Court of India, it is also about a brilliant scientist being humiliated, subjected to third degree torture at the behest of some Police officers, then apathetic government and its political conspiracy," Chandrasekhar wrote in his letter.
"Nambi Narayanan was a senior scientist at the ISRO, in-charge of the cryogenics division, making rapid progress in the field of liquid technology - a key technology in rocket propulsion that is being deployed in GSLV. He was one of the chief architects of the 'Vikas' engine that is at the heart of India's rockets, the same ones that made missions like Chandrayaan and Mangalyaan possible and which will be involved in many more space voyages in future. Vikram Sarabhai, the celebrated scientist and father of Indian Space, put his trust in Narayanan and sent him to Princeton University for higher studies on rocket propulsion," he added.
Narayanan, who was arrested in 1994 for allegedly selling vital Indian space technology secrets to Pakistan, was charged with espionage. He was in kept in the police custody for 50 days.
On September 14, the Supreme Court cleared him of spy charges and termed his arrest as "needless" and "unnecessary". It also announced setting up of a committee which would be headed by retired Supreme Court judge DK Jain to investigate into the role of Kerala police officials in the arrest of Narayanan.
The apex court also directed the Kerala government to pay compensation of Rs 50 lakh to him. The Kerala government on September 27 decided to pay the compensation.
