A staffer of Kotak Mahindra Bank was arrested by Pune rural police in connection with a case filed by a Lonavala-based hotelier accusing the private lender of charging higher than the promised rate interest on a loan he had taken in 2013, an official said on Monday.

While hotelier Ashok Purohit has named seven people, including Kotak Mahindra CEO Uday Kotak, in his complaint, Inspector Sitaram Dubal of Lonavala police station said the latter had no role to play in the case.
