Confirming that Sunanda Pushkar Tharoor died of ‘poisoning’, sub-divisional magistrate (SDM) on Tuesday directed Delhi Police to start investigating whether the poisoning was accidental, suicidal or homicidal.

The doctors and the SDM, however, did not disclose the exact substance that caused the ‘poisoning’ as both are awaiting the toxicology report of the viscera. The viscera report, which normally takes many weeks or even months, would most likely be submitted soon in this case.

The SDM handed over his report to Delhi Police at his Kapasera office on Tuesday afternoon in which statements of 11 people were recorded. According to the report none of the family members of Sunanda, whose statement was recorded levelled any allegation of ‘dowry or domestic violence’ against Union minister Shashi Tharoor. Senior doctors at AIIMS, however, mentioned that injury marks on body of Sunanda, reflect that she had physical confrontation with somebody, a few hours before her death.

“I have submitted the report to the police. I have directed them to examine the case further. None of her family members made any dowry allegations against Shashi Tharoor,” SDM, Alok Sharma, told dna. The SDM was conducting an inquest proceedings in the case under section 176 of CrPC and has established that cause of death was ‘poisoning’ and ruling out dowry angle in the case, which was being probed as the marriage was less than seven years old. “The case is not closed yet,” he added.

The SDM has recorded statements of Shashi Tharoor, his personal assistant Rajesh Kumar, his consultant Shiv Kumar, Sunanda’s two brothers, Rajesh and Ashish, her son, Shiv Menon, two doctors, personal assistant of Sunnada, Narayan, driver Bajrangi and senior journalist Nalini Singh.

Narayan, who had accompanied Sunanda to Kerela earlier this month, in his statement to SDM has confirmed that the couple had strained relationship and were fighting, which often turned ‘loud and sometimes physical.’

However, Sunanda’s brother Rajesh, in his statement to police has maintained that she never complained about Tharoor and was happy with the marriage. Apart from three major injury on wrist, chin and neck, doctors at AIIMS claim that she had more than a dozen brazen scuffle marks on the upper part of her body.

Nalini in her two-page statement to SDM stated that Sunanda had called her around 12:10am on January 17 and was crying. She also mentioned Tharoor’s alleged relationship with Pakistani journalist Mehr Tarar.

Delhi police would now be re-examining the CCTV footage of the hotel, mobile phones of Sunanda and call detail records of everybody involved in the case. Police would also be scanning the laptop Sunanda and Tharoor to get more details of the conversations.
