Justice Kalidas Mukherjee, one of the two Calcutta High Court judges who upheld the death sentence of don Aftab Ansari in the 2002 Amercian Center case, has received a threat letter following which his security has been enhanced, police said today.
The judge filed a complaint on Friday on threats held out to him for upholding Ansari's death sentence on February fifth, Deputy Commissioner of Kolkata Police, Detective Department, Damayanti Sen said.
"We are verifying the contents of the letter addressed to the judge and the sender's identity and motive," she said.
