Peter Mukerjea on Tuesday was sent to judicial custody till December 14 in connection with the Sheena Bora murder case.
This was the fifth time he was produced before the magistrate since his arrest on November 19.
CBI did not seek extension of police custody. Peter, however, expressed no objection on the extension of police custody.
In their earlier remand applications the CBI cited financial transactions, Peter's misleading comments to his son Rahul about Sheena's absence and his polygraph test as grounds for his custody.

However, on Tuesday as there were no fresh grounds, the agency insisted on extending his judicial custody.
Apart from Peter, all the other accused in the case, Indrani Mukerjea, Sanjeev Khanna and Shyamvar Rai, are also in judicial custody. The other three accused are slated to be produced in the sessions court on December 3.
While a charge sheet has been filed against Indrani, Sanjeev and Shyamvar, an additional charge sheet against Peter is awaited.
