The arrested accused included Sunkuru Neelamadhav Subudi (34), his mother and others.
ACP P Ramachandra Rao said that Neelamadhav obtained some fake gold jewellery with the help of his friends who owned a jewellery store in Bhubaneswar in Odisha.
In collusion with the gold appraisers working for Kotak Mahindra Bank, he made his mother and few others pledge this jewellery and take a loan of Rs six crore in all.
The bank authorities realised it was a fraud when the borrowers defaulted on repayment.
