RJD leader Tejashwi Yadav has dared Bihar CM Nitish Kumar to either arrest him or order a CBI probe into the murder of a Dalit leader in which he has been named. Tejashwi's elder brother Tej Pratap and four others have been named in connection with the murder of Dalit leader Shakti Malik in Bihar's Purnea district. But police have reportedly not found any evidence to link Yadav brothers to the murder. Shakti Malik was shot dead on Sunday by three unidentified men riding motorcycles. A video later emerged on social media showing a confrontation between Malik and Tejashwi Yadav.
