Patna, Jan 19 : In wake of a Bihar government official being brutally assaulted by a number of men, including his kin, Deputy Chief Minister Tejashwi Yadav on Thursday said that stringent action will be taken against the accused. "When the matter came to my knowledge, I called Patna SSP Rajiv Mishra and asked him to take strong action against the culprits. I told him that whoever would be the guilty, even from my family or relatives, should be punished in the strongest possible manner. You people do not know Tejashwi Yadav. I never stand with the accused," he said.
