Delhi police have sought details of phone messages on Sunanda Pushka's phone (File)
Delhi Police today approached Canada's Department of Justice seeking details of deleted chats from the phones of Sunanda Pushkar, wife of former External Affairs Minister Shashi Tharoor, who was found dead in a hotel in 2014. Ms Pushkar was a Canadian citizen.
The police sent a Letters Rogatory to the Canadian authorities after the manufacturers of Ms Pushkar's Blackberry phone - Research in Motion Ltd - refused to share the information without the Canadian government's intervention.
Senior journalist Nalini Singh had alleged that she had a conversation over chat with Ms Pushkar before her sudden death in which she had mentioned that Mr Tharoor was close with Pakistani journalist Meher Tarar and the two would regularly exchange messages.
51-year-old Sunanda Pushkar was found dead on the night of January 17, 2014, a day after her public spat with Ms Tarar over her alleged affair with Mr Tharoor. In 2015, the police registered a case of murder connection in her death.
Several persons including Mr Tharoor have been questioned in connection with her death. The police also conducted polygraph tests on six persons, all prime witnesses in the case including Mr Tharoor's domestic help Narayan Singh, his driver Bajrangi, and Sanjay Dewan a close friend of the couple.
Among other causes being probed for her death, the US Federal Bureau of Investigation virtually ruled out 'polonium poisoning' last year after the police failed to draw any conclusion on basis its findings.
A medical board constituted for examining the cause of Ms Pushkar's death is yet to submit its report.
