New Delhi, Feb 22 (IANS): The CBI on Thursday continued questioning Rotomac owner Vikram Kothari and his son Rahul in connection with the Rs 3,695 crore loan default case.

A senior Central Bureau of Investigation (CBI) official confirmed that the two were being questioned again on Thursday.

This is the fourth consecutive day of their questioning. On the first two days the probe agency quized them and searched their residences and office premises in Kanpur, Uttar Pradesh.

The Wednesday's questioning here went on for over nine hours as the Income Tax Department attached four immovable properties of Kothari, three in Kanpur and one in Ahmedabad, Gujarat.

Besides the two, the pen company owner's wife Sadhana, staff and house keeper were also questioned after the Bank of Baroda filed a complaint of loan default against the Kotharis on Sunday night.

Several belongings, including their laptops and mobile phones, were confiscated by the agency on Tuesday.

A consortium of seven banks had extended multi-crore credits to the Kanpur-based firm and its related companies from 2008 onwards. Kothari is the Chairman and Managing Director of Rotomac, while his wife and son are directors of the company.
