Shares of Bank of Maharashtra may come under pressure following reports of the arrest of its chief and other key persons. Reports indicate that BoM Chairman and Managing Director Ravindra Marathe, along with five others, have been arrested for extending fraudulent loans to Pune-based DSK Group. DS Kulkarni and his wife Hemanti were arrested in February in this connection. The BSE has sought a response to this report from BoM and is awaiting the same.
