Sub-Divisional Magistrate Alok Sharma has asked police to find out the cause of poisoning and also to specifically probe murder or suicide angle.
Union Minister Shashi Tharoor on Sunday recorded his statement before the Sub-Divisional Magistrate who is investigating the death of his wife Sunanda Pushkar under mysterious circumstances in a five-star hotel.
There was no trace of alcohol in the body of Sunanda Pushkar though some evidence of presence of anti-depressant drug was likely, sources in the All India Institute of Medical Sciences said on Sunday.
