Jamtara: An FIR has been registered against caretaker Jharkhand Chief Minister Raghubar Das for allegedly making "objectionable" remarks on CM-designate Hemant Soren's caste, police said.

Based on Soren's complaint filed on December 19, a preliminary probe was conducted and then the FIR was registered under the SC/ST Act on Wednesday, Jamtara SP Anshuman Kumar said. "I have filed a complaint against the CM, who used objectionable words on my caste during a poll meeting," Soren had said. "His words hurt my feeling and honour. Is it an offence to take birth in a tribal family?"
