New Delhi, March 12 (IANS): Pakistani journalist Mehr Tarar is likely to be questioned over the murder of Congress MP Shashi Tharoor's wife Sunanda Pushkar, police said on Thursday. Tarar, however, refused to come to India to join the probe.

"Tarar is a relevant person in the case... If necessary, she will be examined," Delhi Police Commissioner B.S. Bassi said of the journalist who was said to be a close friend of Shahsi Tharoor.

Tarar, 47, said she was not ready to come to India but would be happy to answer questions.

"I would like to answer any question Delhi Police have for me but I will not come to India for the probe," Tarar told CNN-IBN over telephone.

Asked why she was being linked to the case, Tarar said: "My biggest mistake was to respond to Sunanda on Twitter...

"If I will be concerned about anything, I will share it with Delhi Police. But no one from Delhi Police has spoken to me so far."

She said she has had no communication with the Congress MP in the past one year.

Tarar's alleged friendship with Tharoor had led to a row between Tharoor and Pushkar.

Pushkar was found dead in a luxury hotel in Delhi on January 17, 2014 under mysterious circumstances.
