A local court yesterday issued the CB-CID, the investigation agency in the case, notice to initiate attachment proceedings against Vikas Choudhry, Shah Nazer, and Anil Balyan, under Section 82 of the CrPC.
The investigation agency has already filed a chargesheet against the three accused in court, said CB-CID Inspector Yogesh Dixit.
Vicky Tyagi was gunned down in the courtroom during a hearing in another case here on February 16, 2015. Shooter Sagar Malik was arrested from the spot while Brijbir Singh was nabbed the next day.
The Uttar Pradesh government had handed over the probe to CB-CID, which, on February 27 last year, had given clean chit to Brijbir, citing lack of evidence against him.
