New Delhi, Feb 8 (ANI): Bharatiya Janata Party (BJP) leader Subramanian Swamy on Sunday alleged that Sunanda Pushkar's murder was carried out by men hired from Dubai and Pakistan, and added that former union minister and Congress leader Shashi Tharoor should undergo custodial interrogation in this case. Pushkar, who married Tharoor in 2010, had checked into The Leela Hotel in Chanakyapuri a day before her death on January 17, 2014. Tharoor's aides said the couple had checked into the luxury hotel because of renovation work at his New Delhi bungalow. Prior to her death, Sunanda was embroiled in a spat with Pakistani journalist Mehr Tarar, whom she accused of stalking her husband.
