Sheena Bora was allegedly strangled in a car and then her body burnt and dumped in a forest in Raigad, about 84 kms from Mumbai.
The CBI today moved the sessions court seeking permission to question the accused in the Sheena Bora murder case in jail.
Indrani Mukerjea, accused of killing her daughter Sheena along with her former husband Sanjeev Khanna and her driver Shyamvar Rai are currently in jail in.
"We seek permission to interrogate the accused in jail for three weeks," CBI special prosecutor Kavita Patil told the court as the of Sheena Bora murder case even as judicial custody of the trio was extended till December 17.
However, Special Judge HS Mahajan is likely to hear the probe agency's plea on Monday.
On November 20, a Metropolitan Magistrate court had transferred the trial in the case to a sessions court and had directed that the three accused be produced there on December 3.
According to the CBI sources, they have received the forensic laboratory report on the Skype communication and messages amongst the trio.
"We need to confront the accused with these FSL reports," they said.
Meanwhile, Ms Mukerjea, through her lawyer, moved an application seeking statements of witnesses recorded before the court.
The 43-year-old has also sought Mr Rai's confessional statement in the case. The court will hear this application too on Monday.
The trio were chargesheeted after their arrest in the case in August this year. Ms Mukerjea's husband and former media baron Peter Mukerjea is in judicial custody till December 14.
He was arrested on November 19 and was subsequently subjected to sustained grilling and polygraph test during his 11-day CBI custody.
