Sources said trades of Rs 2,000 crore were executed on Friday by five entities, including a large bull trader, after they got a whiff of the exit polls before these came into the public domain.
The Sensex had jumped 600 points on Friday on hopes exit polls would indicate a victory for the Narendra Modi-led Bharatiya Janata Party.
Heavy buying was done by these entities in the futures and options segment. "We have issued a notice to the broker questioning the source of income for this purchase," said an official source.
