In the extortion case, the police had earlier told the

court that on continuous monitoring, one of the numbers was found being used by inmates of Tihar Jail including Shukla while the other number was being used by Arun Kumar and both the numbers were in contact with each other. On January 24, Rajender had registered a case in Crime Branch Delhi which was later transfered to the Special Cell as it had already intercepted the mobile numbers, the court was told. Arun, who had allegedly extorted Rs 50,000 from Rajender on January 25, was nabbed by police on January 27. Arun disclosed that while working as a compounder in dispensary at Tihar Jail, he came in contact with Shukla and developed friendship with him. He also procured a mobile phone and SIM for Shukla from which he used to make extortion calls. Police said on January 25 Arun had received a call from Shukla directing him to collect money from Rajender and Rs 44,000 was recovered by the probe agency at his instance.
