The mystery behind Sunanda Pushkar death case is deepening day by day. On Saturday, Delhi Police quizzed Congress MP and her husband Shashi Tharoor for nearly five hours.
However, the Congress MP said he doesn't suspect foul play in death and claimed that his wife died due to medication.
Earlier, the FBI lab which analysed Sunanda's viscera sample, had said that she may have died of an overdose of either anti-anxiety drug alprax or local anesthetic lidocaine. But still things are not clear over her death.
The report suggested she died due to poisoning but denied of any radioactive material or alcohol abuse.
Strips of alprax were found near Pushkar's body by investigators. She was found dead at a five star hotel in south Delhi on January 17, 2014
Earlier, Tharoor has been already been questioned thrice in the murder case.
