Indrani, her driver Shyam Rai and Khanna were interrogated at Khar Police Station on Saturday.


During the course of the grilling, they blamed each other for the crime, a police official said. Police said Khanna and Indrani were giving evasive replies during interrogation.


Indrani's son and Sheena's brother Mikhail Bora was also questioned at a hotel in Bandra on Saturday.Police are also probing Mikhail's claim that just hours before Indrani and Sanjeev met Sheena on April 24, 2012 and took her for what would be the last drive of her life, Indrani had also allegedly drugged him.


By the time they came back, the suspicious, groggy Mikhail had fled. Meanwhile, the car in which Sheena Bora was allegedly killed was yesterday traced, while questions cropped up about a cover-up by police in not registering a case of murder or accidental death three years back when a partially-burnt body, believed to be hers, was found.
