The market regulator , Securities and Exchange Board of India (Sebi), is reportedly investigating whether any big corporate, which fell prey to the fraudulent scheme launched by the fraudster, Shiv Raj Puri , did so deliberately to avoid financial loss due to fluctuation in the share market.

The Sebi team that was camping in Gurgaon for the past two days went back on Sunday. However, investigators said that the team members could visit Gurgaon once again on Monday to question Puri to get more details. This case involves the interest of some corporates and our understanding of it is inadequate. The Sebi team is investigating those critical issues, said a senior police officer investigating the case.

We are probing the case taking the help of experts in this field. We will disclose details of our findings soon, said DCP (crime) Mitesh Jain, who reached DLF-II police station late on Sunday evening to interrogate Shiv Raj Puri.

However, cops did not disclose any details of whether they are going to question the top officials of corporate houses, which have been defrauded by Puri, to find out what commission the accused promised him for investing to the tune of crores.

Meanwhile, police carried out raids at two locations in Gurgaon to nab Puris parents, but could not find them. But we are hopeful of catching them soon. Their disclosure, particularly of his father, will help us get more details of where the money taken from investors by Puri is still parked, an investigator said.

Police officers said that they have already interacted with the disgraced bankers grandparents Prem Nath and Sheela Prem Nath.

They have told us that they were unaware of Puris activities and have no information about their accounts. All accounts were being operated by the accused. He was also managing all the transactions, said a senior police officer. Police have already said that they would not summon Puris aged grandparents to the police station for interrogation.

Latein theevening Puri swifeNidhi Uppal distanced herself from his alleged misdeed. We have no knowledge of anything that you are talking about, she said.
