NEW DELHI: Sunanda Pushkar's son Shiv Menon on Thursday joined the SIT investigations.

Shiv, who had earlier failed to turn up for questioning, arrived at SIT's office to join the probe.

Shiv, who stays in Dubai, had sought some time to appear before the SIT.

Shiv Menon had earlier said that he does not think that his mother could have committed suicide. He had also said that he doesn't think that Tharoor could not have harmed Sunanda. Menon had instead blamed an unfortunate combination of stress induced by the media, and a wrong mix of different medications behind her death.
