A private bus carrying migrant workers and their family members from Jharkhand to Lucknow went off NH12 at Rupahar near here on Wednesday night, injuring many of the 70-odd passengers.

North Dinajpur district police chief Sana Akhtar said the bus had rammed into a small vehicle and then fallen into a ditch. “We have admitted around 40 passengers to Raiganj Government Medical College and Hospital. The bus is yet to be pulled out of the ditch,” Akhtar said.
