The Special Investigating Team (SIT) of the Delhi Police has widened its investigation into the Sunanda Pushkar case.
The Delhi Police has decided to question the doctors who had examined her at Kerala Institute of Medical Sciences (KIMS) hospital in Thiruvananthapuram, said sources.
Sunanda, who had undergone treatment at the hospital before she came to New Delhi, was found dead in a hotel in 2014.
A final report submitted by All India Institute of Medical Sciences in January had stated that Sunanda died of unnatural causes.
The Delhi Police has intensified the probe into the mysterious death of Sunanda. Three days ago, a team of sleuths visited the chemist shops in the Lodhi Road area of the national capital to inquire as to what medicines, if any, were purchased that had brought Sunanda’s life to an end on January 17, 2014.
The police officers had re-examined Tharoor’s family driver Bajrangi, personal staff Narayan Singh and family friends in order to identify the possible suspects in the case.
