New Delhi: Mehr Tarar, a Pakistani columnist who was under the lens in the Sunanda Pushkar death case, has been questioned, sources in the Delhi Police have said.
News agency ANI quoted Delhi Police sources as saying that Tarar was questioned by the Special Investigation Team (SIT) probing the case in the last week of February.
Source said the Pakistan-based journalist was questioned about the bitter fight she had with Sunanda on Twitter in January-February 2014 shortly before her death.
Sunanda was high-profile Congress MP Shashi Tharoor's wife.
During questioning, Tarar denied that she had any 'proximity' or 'relationship' with the Indian politician.
Tarar was also told about allegations levelled by Sunanda's close friend, TV journalist Nalini Singh, during the questioning, ANI reported on Monday.
As per The Times of India, Tarar was questioned at a five-star hotel in central Delhi for several hours.
The police had written to her last December asking her to come to India to assist in the probe, the newspaper said.
Sunanda was found dead inside her suite at a five-star hotel here on January 17, 2014, a day after she was involved in a spat with Mehr Tarar on Twitter over the latter's alleged affair with Tharoor, the Congress MP from Thiruvananthapuram.
Her viscera samples were sent to the FBI lab in Washington DC in February last year to determine the kind of poison that killed her after an AIIMS medical board identified poisoning as the reason behind her death.
The FBI had endorsed the AIIMS report on poisoning and also said that a "dangerous chemical" was present in her body that may have killed her.
