New Delhi: Rotomac Pens owner Vikram Kothari seems to be in deep soup as Central Bureau of Investigation's (CBI) raid in his residence was underway for more than 20 hours.

After the Nirav Modi-PNB scam, the banking sector took another big hit with Rotomac pen promoter Vikram Kothari allegedly swindling Rs 3,695 crore from banks, prompting central probe agencies to register cases, question him and carry out searches at his Kanpur premises on Monday.

CBI and the Enforcement Directorate (ED) are already probing two complaints from the Punjab National Bank (PNB) against billionaire diamantaire Nirav Modi and a jewellery company alleging fraudulent transactions worth about Rs 11,400 crore.

The agency is questioning Kothari, his wife and son.
