The mob made an abortive attempt to take the two from the police custody and when the CRPF on duty prevented them from doing so, they pelted stones on the guards. When attempt to disperse the mob by firing in the air failed, the CRPF resorted to firing, in which three tribals were seriously wounded. One of them later succumbed on way to the MKCG Medical College and Hospital.
Two other injured had been admitted to hospital.
Senior police officials along with reinforcement later rushed to the spot to contain further violence. The agitated tribals have meanwhile, blocked the road by felling trees, police added.
