Police have also questioned the hotel staff.
Sunanda Pushkar, wife of Minister of State for Human Resource Shashi Tharoor, was found dead under mysterious circumstances in her room at The Leela Palace hotel in south Delhi Friday.
Her death came barely 24 hours after the two declared they were “happily married” following public airing of tweets that hinted at an extra-marital relationship and alleged involvement of a Pakistani woman.
“The records of telephonic calls made by Sunanda Pushkar, both from her cell phone and the land line phone of room number 345 (where she and Shashi Tharoor had checked in a day before) have been collected,” a police official said.
Experts from the Forensic Science Laboratory (FSL) have also picked up evidence from the room.
According to police, between 8-8.30 p.m., Shashi Tharoor entered his hotel room. He found that the main hall of the suite was open but her bedroom was locked from inside.
