If a victim of a crime or a witness is cooperating with the prosecuting attorney in a criminal case and reasonably apprehends that he or she may suffer threats of harm or harm arising out of that cooperation, the sheriff of the county or the chief of police of the city shall, upon the written request of the victim or witness, investigate the circumstances, take adequate measures to protect the victim or witness where appropriate, and inform the victim or witness of the level of protection being provided.
