"We have moved the court seeking permission to conduct voice sampling on Mukerjea. The court issued a production warrant and she is likely to be produced in the court tomorrow," said a CBI official.
The voice sampling was required as CBI had got hold of some call recordings which featured her, he said.
Meanwhile, Mukerjea's former driver and co-accused Shyamvar Rai was produced in the court today following his October 19 letter where he had said he wanted to reveal some "truths" to the court regarding the Sheena Bora murdedr case.
Mukerjea, her former husband Sanjeev Khanna and Rai are currently in judicial custody in connection with the case.
