Aug 27 2015 : The Times of India (Mumbai) It was her daughter Indrani killed, not sister, for `affair' with step-brother: Police  Ahmed Ali  Mumbai:    2nd Husband Too Held For Role In Strangling Sheena The case involving the arrest of Indrani Mukerjea (43), the high-profile co-founder of a broadcast company , for the murder of Sheena Bora in 2012 got a bizarre twist in the tail on Wednesday as it emerged that the murder victim was not Indrani's sister but her own daughter. Adding to the sordid saga was the arrest of Indrani's ex-husband Sanjeev Khanna and her driver Shyam Rai by Mumbai police for strangling Bora and disposing of the body in the forest areas of Raigad.Indrani was arrested on Tuesday after Rai, arrested in an illegal arms case, spilled the beans on the murder that had not been cracked for three years. Indrani had all along maintained, even to her third husband Peter Mukerjea, earlier CEO of Star India and pro moter of INX Media, that Sheena was her sister and had moved to the US in April 2012. Police commissioner Rakesh Maria said Indrani had confessed on Wednesday that Sheena was actually her daughter from her first marriage in Guwahati and that she had killed her with the help of her second husband, Khanna. Police suspect it to be an `honour killing' as they say Indrani had serious problems with Sheena's relationship with her step-brother Rahul, Mukerjea's son from an earlier marriage. Sheena and Rahul were planning to marry , police said. However, police are also saying there could be a financial motive linked to proceeds from the TV channel where the Mukerjeas were the power couple. The third theory they are examining is whether Sheena was blackmailing Indrani by threatening to reveal to Peter Mukerjea that she was her daughter and not sister. Police sources said that after killing Sheena, Indrani and Khanna had also planned to kill Michail, Sheena's brother and Indrani's second child from her first marriage, in order to garner his property . Khanna's motive for involvement, according to the police, was that he wanted his own daughter from Indrani, Vidhie, to get Sheena's share of the mother's property . Khanna will be produced in court on Thursday . Rahul, who arrived in Mumbai late Wednesday evening, was being grilled by Khar police, who are probing the case, at the time of going to press. He had dropped Sheena outside National College in Bandra on April 24, 2012 from where Indrani and Khanna picked her up in their car before strangling her. 'Great Gatsby' of Mumbai Indrani Mukerjea was like the Great Gatsby of Mumbai--no one knew where she came from and how she overnight transformed herself into a self proclaimed media maharani. Those who knew the Mukerjeas suggest that Peter was a different man before he met her and that she had him “under her thumb“. A relative of Peter's told an acquaintance recently that his wife was his undoing. “There was something diabolical in her eyes,“ said a former employee of NewsX. However, other friends describe Indrani as a warm down-to -earth person. Rai told police that Indrani had asked Sheena to meet her outside National College under the pretext of discussing some important issue. “Indrani insisted over the phone that she come alone. After Rahul dropped Sheena at the spot and left, Sheena saw Khanna sitting on the rear seat of Indrani's car and refused to get in. But Indrani pulled Sheena inside and the car took off, with Rai driving,“ a police officer said. On the way , while Khanna caught her hands and legs, Indrani strangled her. “The trio took her body to a remote place in Pen and used petrol to burn the body so she could not be recognized,“ said Maria, who was instrumental in cracking the case and who himself interrogated Indrani on Tuesday . This case too would have gone undetected like a few other sensational murders including that of 58-year-old Lalita Pinge in Shivaji Park in 2007, had Maria not asked inspector Dinesh Kadam to act on the tip-off that Indrani could be behind the mysterious disappearance of her sister Sheena. Police have now called for the call detail reports (CDRs) of Indrani, Khanna, Rai, Sheena and Rahul. A former editor and columnist is also likely to be called in for questioning as he was in touch with Indrani. Police said that after Sheena went missing, Rahul tried to call her on her cell phone but it was switched off. After waiting for two days, he went to Khar police station and tried to lodge a missing person's complaint as Sheena was a Khar resident. Khar police, however, did not take any notice, after which Rahul approached Worli police as Indrani stayed in Worli. The Worli police went to Indrani's house, where the latter told them that Sheena had left for the US “for her future,“ and the police believed her.The next day , Rahul got several text messages from Sheena's cell number stating that she wanted to break off the relationship with him as she was shifting to the US. Rahul tried to approach her again but could not get in touch with her. Maria is said to be upset with Khar police who did not take Rahul's complaint seriously and also with two senior police officials of the region who were not convinced about information on the murder until Maria called them and asked them to supervise the investigation. Peter Mukerjea told the police and media on Wednesday that he had never known that Indrani had a second husband.“She told me Sanjeev Khanna was her first husband and I believed her. I don't know anything about her marriage to any other person. Indrani and Khanna used to talk, but I never bothered to find out what went on between them. I am shocked. When, two years ago, somebody told me Sheena was her daughter and not her sister, I thought it was rubbish and believed Indrani,“ he said. Siddhart Das from Guwahati was Indrani's first husband. Cops are also examining atheory that she had one more relationship before that and whether that ended in marriage or not. Meanwhile, a team of police officers on Wednesday reached Pen and collected the copy of the panchnama and pictures of the body. “We have communicated with SP Suhez Haq who had told us that on May 23, 2012, police had indeed found the decomposed body of a woman which was beyond recognition. We are in the process of gathering evidence,“ said Deven Bharti, joint CP (law and order). Sheena had been working for Metro One in 2012. A MMOPL spokesperson said on Wednesday that she had “joined Mumbai Metro as an assistant manager on 20th June, 2011. She took leave of absence on 24th April, 2012 and while she was on leave, she sent in her written resignation.“ Maria has congratulated police inspector Dinesh Kadam, whose informant came up with the tip-off about Rai possessing an illegal weapon. Based on this, ACP Sanjay Kadam, senior inspector D Bargude, and Nitin Alaknure and Nyaneshwar Ganware worked on the case. (With inputs from V Narayan)
