Khan, arrested in a case of tax evasion and lodged in Mumbai's Arthur jail, was produced before the CJM here.
The court had issued a production warrant against him in an FIR lodged here in 2011.
The matter relates to issue of a passport from Patna in December 2010 on the basis of alleged wrong information furnished in the application. Khan had applied for a passport in 2007.
After detecting irregularities, the Patna Passport office had registered an FIR at the Kotwali police station in 2011.
Khan had hit the headlines recently in connection with a tax evasion case. He was alleged to have siphoned off a huge sum of money abroad without paying tax.
