A special court for CBI cases here on Thursday separated the trial of two accused in the Rs 13,500 crore Punjab National Bank (PNB) scam, noting that it was not known how long the extradition process of diamond merchant Nirav Modi, a prime accused, would take.

Gokulnath Shetty, a retired PNB officer, and Hemant Bhatt, an authorised signatory of Modi's companies, are in judicial custody since 2018 and their bail pleas have been rejected, the court said.
