Patna police will keep on investigating: KK Singh's advocate

''Part of the cause of action, consequences and complainant were in Bihar so FIR was completely valid. Our law looks for the convenience of the complainant and not of the accused. As far as witnesses are concerned Police team could go and examine anywhere. Patna police will keep on investigating since there is no stay on it,'' says advocate of KK Singh (Sushant Singh Rajput's father).
