Attempting to unravel the motive and the wealth angle in the Sheena Bora murder case, Mumbai police on Friday questioned Vidhie Khanna, the daughter of the prime accused Indrani Mukherjea and her former husband Sanjeev Khanna.
Vidhie was later adopted by Indrani's current husband, former media tycoon Peter Mukherjea.
For the third consecutive day, police also questioned Mukherjea for almost the entire day, posing to him queries pertaining to the family's financial dealings, bank accounts and property matters.
Among others questioned today were his brother Gautam Mukherjea and his wife Aarti.
The trio of Vidhie, Gautam and Aarti Mukherjea were permitted to leave after the questioning around 8.30 p.m., but Peter was still inside the Khar Police Station.
As the police attempt to unearth the motive behind Sheena's killing, the three main accused arrested so far in the murder case - Indrani, Khanna and driver Shyamvar Rai - will be produced before the court on Saturday for extension of police custody, as the current spell granted on Monday lapses then.
However, it is not yet clear whether police will get continued custody or the accused may be sent to judicial custody.
Police have reportedly not succeed in extracting any admission of guilt by Indrani, though last week, police claimed that Khanna admitted to his complicity in the Sheena Bora killing.
Besides the trio arrested so far, Mumbai police have not arrested any other persons in connection with the case.
Several people have been questioned in Mumbai, Kolkata and Guwahati, mostly related to each other out of Indrani's marriages and her affair with Siddhartha Das in college resulting in the birth out of wedlock of Sheena and her brother Mikhail Bora.
The Raigad police is carrying out a separate probe into the circumstances and alleged lapses whereby no police complaint or FIR was lodged after Sheena's body remains were found near Gagode village, near Pen, around 95 kms south of Mumbai.
Police are also awaiting the DNA tests and forensic reports of the accused and victim's purported remains recovered from Raigad last Friday.
