A total of nine people were admitted to a hospital in Malda district after they were rescued, the District Magistrate (DM) of Malda, Kaushik Bhattacharya had said.

A boat carrying close to 80 people had capsized in the river on Thursday when residents of Wajidpur village in Bihar were returning after shopping in Rampur Haat market of the adjoining state, situated right across the river.

Deputy Superintendent of Police of Bihar's Barsoi, Pankaj Kumar, had said, "Prima facie, it appears to be a case of overloading. The boat had a capacity of 40 passengers but was carrying almost double the number."

"Many of those riding the boat either swam to safety or were rescued by onlookers. About two dozen people are yet to be traced. Professional divers have been deployed for the purpose."
